Therapist told me expecting reciprocity in a friendship is selfish

I’ve been going a to therapist at my college and brought up how I felt like I keep coming through for my friends when they are in need, but when I’m in need and ask for their help they always tell me no. When I told her I was getting upset because I felt like I was being taken advantage of she called me selfish. She said that I was being intolerant of their beliefs since they clearly don’t value loyalty and standing by people as much as I do. When I asked her if I would be in the wrong for not standing by them anymore she said yes. I don’t know how to feel about this. Thoughts?
