Today one of my best friends asked me to be bridesmaid in her wedding next year - 

First, I can’t believe someone thinks highly enough of me to put them in their wedding 

Second, I keep thinking i’m going to mess this up somehow. Maybe it’s my anxiety but I feel this impending doom on our relationship.
This woman and I have a wonderful and healthy relationship and so as of right now, nothing could mess it up. I just feel like i’m going to not be friends with her by the time her wedding comes around or i’ll just mess such an important day up for her. Does anyone else feel this way in similar situations? How do you get over these feelings?
Thank you for reading. I hope you’re well.
