lol
I suppose it is some thing that is vey very difficult to get control over.
but it is doable, almost always.

I mean not lol.

I can see that

Depression is a mental illness. You can't just fix it like that because it 'gets old'. :p People don't choose to be depressed.

I know, and I'm not trying to be rude or condescending, It's just a strange concept to me and I want to understand

This main idea is that some dark and depressing idea got stuck deep in your mind, so deeply that you are always thinking about it witout realizing it. Sometimes you don't know what it is.
It is deeply wrot in you mind, it really ruins you.
Also you can' say to someone that is depressed that he ie pathetic, he knows that, he just can't move forward.
Some practices consists in making you realize what this dark thought come from, and you can achieve that by helping other people feeling better (this worked for me).
And if you know what this thing that ruins you is, you have to learn how to live with it, if nobody teach you to live with it, then you'll stay depressed.

Hope it helped you If you want some more information, just note me

Hmm, well, depression is not usually about something bad or dark happening to you, or even being in a dark place mentally. It is very much an illness. A simple way to describe it is, the part of your brain that makes you happy by making serotonin, stops working. Your brain is unable to create the chemicals that make you feel happy and good, so you are thrown into a mental state that you cannot escape from. You can't do things to cheer yourself up, because you literally cannot produce serotonin. It's really hard to get your brain to start working correctly again. Know what I'm sayin?

Sometimes, it's genetic, but in my case, I took on too much and it broke me. I had a nervous breakdown last April. I take one medication for depression and another for anxiety. It can sometimes take months, years or even for the rest of their lives, to deal with depression. Think about how some songs get stuck in your head and multiply it. Imagine not being to concentrate, making mistakes left and right. Crying for the simplest of reasons or crying for nothing at all. Some don't even know that they are depressed because they have always been that way. The only way to diagnose it, is by seeing a therapist, to identify your stressors. From there, you get reffered to a psychiatrist, who is the only one allowed to perscribe medcations/ treatment. It has been a long and difficult road for me. I have come a long way and I could have easily not be here. I wanted to end my life, but I had the strength of will to see that it wasn't normal. Learning I have so much to live for. I hope I have given you some insight on this.

I USED to be like that. Then I thought about the good thinga in life.

Depression comes in all shapes and sizes, and doesn't have to be coupled with a dystopic dark vision of life. It's often symptomatic of other conditions. In my own case, and for some other people I know, it goes hand in hand with anxiety. This is fairly common. In these cases I find that depression is most often triggered by feelings of guilt for ones various shortcomings and failures, fueled by fear (or conviction) of being detrimental to your surroundings (most often friends and loved ones), and consists of a mix of self-loathing and self-accusation for all the former, feelings of defeat and despair in the face of change. In other words to have an irrevokable feeling responsibility for things far beyond the capacity of a single person, and then buckle and suffocate under that pressure. This is all very treatable (I hope) through therapy. In other cases, as described a bit further up, it's more of a chemical condition. I won't say too much on it. Physical inability to feel joy, an eternity of grey. With hue, life loses direction and purpose, and sadly many people with this condition choose to end their lives, not because they feel oh so sad, but becasue life literally holds nothing for them anymore. This is a longer and much tougher route to go and usually requires an extensive regimen of medication. Having lived in squats and otherwise among other undesirables in society, I've seen way too many go down this road to heavy drug abuse and what's worse. Well, in attempt to end this on a brighter note, many people do get properly treated (I would think, the majority), and do get past it.
