Glad you are here. So many of us have been "there"---and back more than once or twice...
(it might be very hard but helpful to find things to do outside of the house, away from the parents/the pain of unmet needs...somehow we have to learn to separate our selves from the judgments/opinions of others we want love and care from so much...)
Hang in there, and you will be helping others too. Just by being, talking, and waking up each day.
