I'm sorry you're having such a hard time at home. It DOES sound like you aren't being validated at home, and that your parents don't fully understand your illness.

You say you haven't had therapy in awhile. You really DO need a therapist, and I would hope that you are trying to find a new one! PLEASE look for a new therapist and get back into therapy. Having someone to talk to is imperative for you. You aren't ready to "graduate" from therapy yet. And there's no shame in that. Many of us have had to have years of therapy. In fact, I spent most of my adult life in therapy, off and on -- and I'm 63!!! Right now, I'm out of therapy, but who knows when I might have to go back in. LOL
So talk to your parents about getting back into therapy, okay?

And just a suggestion. You might have to develop a "thicker skin" as far as what people say, i.e. your parents or sisters because out in the "real world" people are going to say things that MIGHT hurt or upset you and you can't keep quitting jobs just because someone bugs you or says something that upsets you. Bosses are GOING to reprimand you for mistakes made -- supervisors are GOING to make you mad for blaming you for someone else's mistakes -- those things happen. But you cannot keep quitting jobs because of that. You have to learn how to deal & cope with these things. Bad things happen in the 'real world' and there's nothing you can do to stop it. All you can do is cope with it. That's why you need therapy and thick skin.

I wish you the very best. Make a call to a good therapist. Please take care, and God bless. Hugs, Lee
