I am not tracking this, at all.
You pay his rent so he can use his disability check to buy crack. He calls you controlling when you buy him food instead of giving him cash because he wants crack.
You have your own health problems and need professional help to sort this all out but don't have the money because you pay his rent and buy him food so he can spend his disability check on crack.
What is holding you back from changing your phone number and jumping in your care and heading back home? He can't walk so he can't chase you and he's not going to follow you because all his money goes to..... crack.
