I want my confidence back !

Hey everyone! I've been on mfp for awhile now. I haven't used it much, but now I'm ready to start. My confidence has gone down hill. I've gained some weight and I don't like it. My boyfriend is very fit, and it gets so intimidating. I am now 180 and want to get to 145. I was looking around mfp and I noticed how supportive and nice everyone is. I've been wanting to do this for a long time now. I have so much dedication and i can't wait to accomplish my goals.
