I have this friend, and I don't know if I am being unreasonable but it seems to me that everything is on her terms. She used to be a beautiful, friendly person. Nowadays for the majority of the time I feel that she just expects, expects, expects. She only phones me when things have gone wrong, making out that every problem she has is critical and implying that I am the only person that can help. It often turns out to be nothing. I drop everything to help her then she forgets she even asked me because another friend has stepped in. We arrange to do things and she makes excuses then she posts on Instagram pictures of her doing something else. I think she is depressed and very up and down, and part of me feels that I should support her even more but I can't take it any more. All the lies, drama and last minute cancellations. I feel totally used. She never even asks me how I am. Am I being selfish to think this person is a bad friend if she has emotional issues?
