Give me strength

I am such a sucker when it comes to family. I just can't seem to say no. I think I am afraid of them getting mad at me or being dissapointed in me. Why can't I just be an asshole and tell them I don't care. It is not my fault they are in the situation they are in. I did not cause it. Yet I feel obligated to fix it or at least try........
Why can't they just let me live in my own little world secluded from everyone and everything. I don't like reality and it is so much easier not dealing with it. Well the basics I am good with but anything that has drama or involves serious thinking or stress, I just don't want to be there right now. Right now I just want to sleep.........
