before you go to the homeless people, it is good to have thought through why you home is unmanageable to you....
for me, i had a few very valid safety reasons...
1. he was physically violent towards me
2. he fell asleep with cigarettes still burning
3. he'd come in drunk at 3am and start cooking chips and then fall asleep.
just brainstorming here, don't know if you have physical problems as a result of stress in the home...such as use of anti-depressents, etc. or anything that your GP could support you with. in my case, i had a broken shoulder and had requested a psychiatrist to deal with the emotional trauma.
the homeless people never contacted my GP but if you are already working with your GP due to alcoholic trauma, it would help your case.
