Open mouth insert foot!

Well I must admit something that I am sure everyone already knows about me. I have a big mouth! I love to talk! I have passed this problem down to my Ava and wish I had not, but God has a great since of humor! FB has not helped me a all! I tend to put how I am feeling without a filter! I am going to try and quit using FB as a way to vent.My goal in 2013 is to keep my thoughts and feelings to myself. The other problem I have is I expect others to have some kind of niceness about them. I am so dang nice and expect it back. This is killing me. I worry about it all the time. I do not like mean people! My next goal this year is to go back to Church. I pray all day but I feel so horrible not going,  I have a mini panic attack at the thought of going. Not anything like I used to be. I at one time in my life had a very close relationship with God but in the last 4 years I get so nervous at church. Yep the woman who never meets a stranger has social anxieties!Any ideas on how to fix this! I am all ears!
