I have this friend. we have actually become very close. Most of the time I feel really comfortable around her and we can talk about anything... But then there's other times when I'm having a bad day and I don't want to talk to her. I avoid her and talking to her. I just feel so far away when I have a bad day and I don't know what to do. I think she gets offended that I don't want to come to her for comfort, or to talk to. As much as I'd like to feel that trusting of her, I am really afraid she is going to tell someone whatever I tell her. What do I do?
