Questioning my relationshiips again

What is it when it takes will power to not answer a phone call cause you don’t want to be treated like you’re stupid then feel guilty for avoiding someone calling you til the whole cycle starts again. Last night I didn’t answer my friend’s phone call because the night before he kept telling me to write a letter to the president about my mother and her not being able to get hepatitis treatment until there is worse liver damage. Anyhow I have no wish to write such a letter first of all second of all it is a drug addict’s disease and no one would probably care. He goes to hypnotist classes and I wonder sometimes the things he says to me. So I hope for the best for my mother, I tried to help her. And as for my friend I always end up at this place, after his vacation and I cat-sit again, I am going to try to get perspective. Not sure why I posted this? makes me look like I"m “borderline” and i"m not.
