I don’t think it’s selfish to take it personally. It’s pretty normal. I think a lot of us tend to feel this way. It’s hard to see the big picture and especially hard if you’ve never had a very good support system. There are many times I’ve had to really talk myself out of resenting people for not being there for me when I thought they should. I am still trying to be a better friend to myself and not place expectations on others. It’s not easy.
