You could always try just pressing on.
When you sense that the depression is stopping you from doing something you really feel like you should be doing, catch it and do it anyway.
Heck, some of my best pics come from me going through huge art blocks and finally telling myself it's gone on long enough, and that I HAVE to do something about it.
If you can't find inspiration, just take a minute to think over some past ideas, maybe look around your room, at some cards, even looking through other artists' galleries can be helpful in getting the creative juices flowing. =3

And anytime you wanna play a game of Vanguard or just talk, you know how to get in touch with me. |3

I've. been tackling this very issue myself for the past few years. Some fundamental yet powerful pieces to the puzzle include:

--Finding your "why"; finding some larger reason that motivates you on a longer scale
--Starting small, introducing new behaviors in tiny, effortless chunks in your daily routine.
--Allowing yourself to be human, make mistakes, and put out something only partially decent rather than waiting for perfection
--Stop comparing yourself to others.

There's more, but those are some primary principals to follow. I have an excellent book on starting new habits for accomplishing whatever you want to accomplish. I can send you the PDF or EPUB if you want--just note me.

This journal is so me.
I don't work (I just graduated actually), but in general I have little to no motivation to do lots of stuff, and most of my main tasks involve housework (because of classified reasons). I've been getting sick A LOT too, and my parents are really fragile, so nobody really helps the boat flow. Alas, I have to do the first step.
So yeah, my desperation of my current situation fuels me, and it just keeps fueling me until I get my arse up and start working, then break, then work again. And so on.

Ah, the moving on part. I'm exactly like this. I've lost my grandmother too at the start of this year and my dad hasn't been able to snap out of it, and he won't be for long. My mom hasn't snapped 100% out of her parents' deaths either, and it's been 10 and 26 years already. Truth is, the upper two comments are right; you gotta start small, and keep on going small, until it becomes a habit, and then you can go bigger. Allowing yourself to be human is important too (I don't always do that but it actually saves me from lots of things when I do) and stopping comparing oneself to others is the most important thing of all. You're for you and no one else, so you gotta take care of that self for you. Just give yourself a little push when you don't feel like it; not a forced one either. A gradual and tiny bit one.

That's pretty much my two cents on this journal, I feel like I relate sort of so I hope I have helped somehow

This winter I was in sort of a funk. I found my phone has a pedometer in a health app. I started to go for walks around my neighborhood every other day then more frequently. I'm an engineer so I like numbers and data. It was fun for a few weeks to try to see how many steps I take in a day and working up to hitting the target. The app demands I take 10k steps but that's 5.5 miles for my legs. I typically walk around 4k in a normal day.

Then after 2-3 weeks I realized I really enjoyed the walks and I was looking forward to them. (I used to walk back and forth to campus when I was a student and then occasionally when I lived in town and could walk to the store but I live in a suburban area now and there's no where to walk to.) I experimented and pushed the weights around and that turned into full blown weight lifting again. The first two weeks were super sore and miserable but I make sure to stretch well and I've noticed I've definitely gotten more flexible in a short period of time. Working out feels really good. Better than peeling the banana to be honest because each lift is a tiny investment that will add up to something awesome. I bought a big dry erase board to keep track of my plan and numbers in my garage.

Don't give yourself absolutes, like "I have to draw today! I must write!". If the mood hits let yourself go but don't make yourself. You're setting yourself up to fail if you don't do the thing and then you feel bad about failing.

I've been writers blocked for a while. Staring at a blank word document. I've read tips like start writing a journal entry or describe your day or what you see or just a description to get your fingers moving and then see what happens. Drawing could be similar. (I want to see more drawings you come up with, no pressure haha.)

It's awful when a loved one dies. The worst part is this person's life ended and the world just continues on. The wind still blows, birds chirp. Cars go by. It's ok to be happy again. It doesn't diminish your mom or mean that she isn't missed or loved.

I've read books on stoicism. Stoicism would say to focus on all the positives and be thankful for what you and she did and do have and be grateful that it wasn't worse. This isn't meant to be offensive if it comes off that way. Focus on all the times you did have and all the memories and things you did together. Things could have easily happened totally differently through dumb chance and you might not have those things. Be happy she had the life she had compared to all the lives that are lived and she had you all as family of all the people she could have had. Be happy she was able to have you as her son! Have your sadness but also take a step or two to move forward and do new things in honor of your mom and her memory. Carry on her spirit in new things you do and places you go. Build something she'd be proud of you doing.

It's sort of goofy but think of this: she got to live in modern times in the US. Of all the lives people have lived, she didn't have to live in ancient times or the middle ages, or starve, or be a peasant, or a slave, or a life full of suffering and misery, or be in a war or a refugee. She got to experience music, tv, lightbulbs, movies, airplanes, vacations, microwaves, plastics, cheap oil, vaccines stopping common diseases, fresh food year round, indoor plumbing, cities that weren't full of horse poo, air conditioning, cars, factory made clothing, voting...y'know? Not even kings experienced those luxuries before.

Do you do artistic stuff for work? I also usually feel like unwinding after work rather than going out in the evenings or doing something intensive. Drop me a note sometime.
