Oh dear this is a hard situatuon. What can you do. Well you can just straight out say that you feel that it is not good for either of you to stay friends, trying ot explain how you feel he is so critical. You could also say that you understand his problems with his health but that you dont feel you are helping him in anyway and he does not help you. This is the honest approach. Avoiding all swear words but saying that you feel this is the best option.

Or you could just try and stop being in contact and ignore him, not a nice one. Or wait a while to tell him, give yourself some breathing space and write a letter from your heart. Dont do it when you feel pressured by him or just after you have go something from him insulting you, if this is possible.

I must say I am not a good person to give advice as I have just had to deal with a situation whenere I had to loose two friends for hte good of my health and I was rather pressured and pushed in to a corner by the both of them so how I wrote the letter maybe was not a kind as it could have been, But I tried to think with my head, keep it honest and avoid too much emational content.

I dont know if this helps at all.

Main thing is this. You have to protect yourself and you have aright not to be insulted or be a punch bag for someone no matter what situation they are in. You need ot move on now and you must do so.
