Looks to me what you need to do is NOT to leave the house or commit suicide, but find a good lawyer/attorney. You do not need that kind of unsupportive people around you. Being disabled, you are not the one who should leave the house. Dont let her take you down even more then she already did. Enough is enough right? Go seek the help you need, find yourself a good attorney and make the torture end now.
What youre going through is not easy, but know that many of us went through similar stuff and while it looked like the end of the world at first, it was for the better in the end. You have people around who care about you, focus your energies towards them, and get rid of the others.
Youve already gone through a lot of difficult moments, youve proven to us that youre strong. Use some of that strenght, go get yourself an attorney, and start making the changes you need. Dont wait anymore.
