Poor u. I feel really really sorry for u but i do agree with what everyone else is saying bout the drink wont help and im sorry to say this but it wont it will only makes things seem worse then u will go and dosomething u regret.
I was just wondereing if youd thought bout totally moving away from the situation to somewhere compleatly differant like nottingam for example? I can understand you perhaps wont to still be near your daughter but it might make makes things more bearable if u where to move on and make a new life for self then at least your actually out of the problem.

Anyway i hope things work themsleves out for you and keep in touch and let us know how things go and what u decide to do. Afterall the way i see it u cant stay around there for much longer and carry on with the way things are.
