I am in a dilemna and can't sleep so I am on here getting opinions and suggestions, my daughter is 31 and has?

two sons, one by her ex husband and another unmarried by a druggie loser, I had alot of health issues myself and had to leave state to reunite with my husband and for the last 4 yrs I have finally gotten to a place of peace, my daughter is a mess, she at last got a free apartment and had the state helping her and she had a fresh new start but against everyone's advice she got back with her druggie boyfriend and now lost her free apt, and thinks she's pregnaunt again, living with friends, and kicked off of aid, she wants to come live with me, I am on disability and my husband does'nt make alot of money, so I am sleepless, worried and don't know how I can take care of her, she is really loud and messy, I love my daughter and do want to help her but its hard thanks for any comments
