Why am I always left out and slighted?

It's not self indulgent. You're seeking help because you need it. I don't think you should leave those groups so quickly. Just wait for..... at least a week before leaving. You could try and keep (your mind) busy. Like if you have hobbies, you could do something fun or productive. It's what I do, I just try to do something productive, cause I know things get worst when I'm not doing anything. I hope your requests get acknowledged, and I hope you start feeling better soon.
