I'm glad my advice could help! And for this topic, it's a little nice to see someone who at least has some real-life experiences with those who suffer mental illnesses. With such knowledge at hand, I bet you could do a good job representing the topic.
I was just giving out advice in general if you didn't have those experiences to draw on. I unfortunately see a lot of people (teenagers, mostly) who want to write about mental illness, not because they have anything to say about it, but because they want to write something "dark" and "edgy". Many of these people have no connection to it in real life and haven't done any more research than using Web MD and wikipedia. They often represent it in a really romanticized and offensive way, not knowing that they're doing so because that's what a lot of popular media does.
Also, it makes me happy that you seem to be writing about mental illness because it's something that's been a part of your life and not just because you think it's edgy. The experiences that you've described are exactly the type of things that bad writers leave out because it isn't cool or sensible.
Good luck with your story! I'll probably be writing that guide after I finish the one I'm currently doing. It's a topic that means a lot to me, and hopefully it'll be helpful!
