I'm having problems talking about how I feel to my best friend. It's always a labor for me. I need to know how to become comfortable talking to her about anything and to seriously talk about it. She doesn't like when I don't talk about how I feel and it bugs her extremely every time. I don't want to lose our friendship because I was uncomfortable. PLEASE HELP!

Well if you r truly that uncomfortable then she can't possibly be a true friend otherwise it'd come naturally

How long have you been friends, and how old are you??

Why are you so uncomfortable? How long have you been friends? Has she ever broken your trust or done something to upset you?
