Need reassurance

I was recently slightly offended by somebody’s comments towards me (which was probably nothing really but I am very sensitive) and expressed my feelings to a friend who said she’d speak to me about it later.

When I didn’t hear from her I had kept thinking about the comment that upset me and I got a little annoyed that she hadn’t replied to me. Now I feel I have upset her and made her angry. I have said sorry to her if I had upset her, she hasn’t ignored me altogether but she hasn’t responded to my apology. I just need a sign that she has forgiven me. All I ever wanted from her was some reassurance, my anger and frustration were never on her. She means more to me that she knows, she’s a dear friend.
