Hi I Am A 45 Year Old Black African American

Hi I am a 45 year old black african american man and I have been an alcoholic for years ..practically since my 20's and ever since I have been having major problems with walking especially walking on slopes (downhill}. I also have problems writing because my fingers shake so bad..so bad I have to have my wife fill out forms for me. By the way I can go for 2 or 3 days without drinking but even after not drinking for a couple of days I cannot even put my pants on without having to hold onto the wall or something. Please help I have no medical insurance.
