I am a bad friend

Lately all of my friends have been getting in my nerve in some way and I honestly know at this point it's something going on with me, but I can't get a second to myself to reflect and think. However what pushed me to this conclusion was today when one of my friends, Mary, said they she broke up with her boyfriend and a few months and had to go pick up her stuff without crying and so on and so on. I looked at the message and felt nothing. As of now I'm the only immediate friend with a car to help, and part of me doesn't even want to help. I'm just so fed up of the same thing from her and her wack ass relationships like she keeps messing with the same type of dudes and acts shocked when the outcomes are the same. This has happened on two other occasions with two different other men. Like at this point I will not let myself feel for her because it's really the SAME SHIT. I'm just tired of everybody and everything. I can't have a minute to myself and nobody is getting how important that is to me. I'm always there for everyone else, but it's getting to the point where I can't be there for MYSELF and it's making me a mean person 😔
