Unfortunately, with mental illnesses, some people just won't understand. A lot of the time the ignorance or making fun of it is a defense mechanism because they don't want to face it. My fiancee struggled with depression and a shitload of other mental illness issues a few years back and one thing that helped her parents understand and know how to handle it was talking to a therapist. Sometimes talking to someone will justify and make it real rather than something you "made up"

We have talked to Therapist about it.
They have sat in a room with me while talking about it.
Even years back when schools called them to tell them.
So at this time, I'm just going to assume they just don't want to deal with it.
I mean, I even get threats from my mom to call the cops if she sees the slightest hint of me being upset with her cause she thinks I want to just skill myself. _{Yes threat. Not worry. She glares at me with a mean look.}

so idk. I'm ready to give up and just try to get away from all of the stress of dealing with them.

When I came out to my family, they responded in much the same way. I just had to get away and give them their time, and it sounds like that might be something you have to do.

As someone diagnosed with severe depression it's a hard thing to explain to someone what it means. I guess the best way would be akin to being constantly tired and not really being bothered to do anything. Most times, I'm out and about putting on a brave face, but at times I'd rather lay in bed alone.

Hmmm
I got once a good explanation, but i try to get it work in english.
Every Person is an barrel, it shows how much stuff we can bare. There are some things that Fill the Barrel. and its gets heavier and heavier to carrym Like bad things that happened, but also genetic, and stuff.
And good things that happen...make holes in the barrel, so we can get rid of this stuff. The Problem is on this thing. Its not easy to get rid of this stuff, and people with depression aren't able to do that so easily, things that help other people can feel like a burden an fill this barrel instead of helping to making it empty.
So anything you do with depression is like you are carrying a big barrel full of stuff with you. Depression can have many symptoms, and only one of them are suicidal thoughts, maybe it could help to find one of this list, and usually you have a major depression when you have 8 of this symptoms, so you can explain your parents what symptoms there are and that this also means depression.
