Thank you hawthersand Tyelperion, DH was the one that finally talked me into it. I'm still terrified of what will happen when I sit down and tell a professional about my home life. I live at home still, with my (separated) parents, two adult brothers, teenage sister and DH, in a 3 bedroom flat - dad is possibly an alcoholic, and verbally abusive to my mum. He also smokes weed constantly. He spends all of his money on beer and weed, contributes minimally to the household, and borrows money from my brothers regularly (he knows better than to ask me any more). The other day he swore at me repeatedly for not saving him enough curry sauce from my pot, because he'd failed to order any of his own. Being in the house with him is incredibly uncomfortable, and I wish he'd just fuck off and leave us all in peace, but of course he won't, and mum won't throw him out on his useless, lazy arse.
I love my mum, but she is useless with money, and we have almost been evicted previously because she hasn't paid the rent, and hasn't told me.
Sorry, I know this isn't the place to complain, but it feels like the pressure is building up, and I don't know what will happen if I blow up.
