Thank you for the replies! I am really thinking about what everyone has said.

Its true that the situation is beyond my control. No matter what I do we do not seem to get along. I guess that is the nature of it.

I am grieving for my Dad still at times, and I am concerned about his work but I feel because he has bi-polar things that are usually easy for people are hard for him and that stresses me out. I am trying to accept that he is where he is. Hes never really been stable so Im not even sure if its an option that he will be stable or if this is just how it is going to be. I really supported him through a 4 year depression and many manic episodes but I need a relationship where the other person can be supportive as well and Im not sure that is ever going to happen!
