Welcome!
I am Christian...have been since I was 10 years old. When I was younger I wound up in some churches that seem to tear people down on a weekly basis with the intention of helping them - the thing that kept me there was glimpses of God that would slip into the sermons preaching fire and damnation. Then I went to some churches (around college age) where people seemed more positive and happier and I was relieved because it was a better place to learn how faith in God can help. About 4 years ago I wound up in a church that helps change lives, loves everybody no matter where they are at, and it has really made a difference and now I am much more inclined to seek God on my own (at home, at work etc. turning my thoughts to him).
For me - my SA has a few different causes (as far I have learned) and they have taken alot of time to address - one after the other.
When "The Purpose Driven Life" was making the rounds in churches in California (where I live) I participated but I wasn't expecting much.
Reading the book - I came across a section that described how people can have a silent rift with God (now there are people who are aware of their rift with God but this is when you think you understand and trust him when you secretly don't). That section of the book led me, along with prayer, revealed to me some old pain in my life that I blamed God for. That part of me healed and then it was on to other painful pieces of my past that contributed to my social anxiety. I started going to counseling (psychologist) and tuned into sermons on the web at my church website (tlc.org) and I kept encoutnering my problems (guilt, blame, trauma) , working through each peice with counseling and church. Basically God has been answering my prayers to "show me things I am not willing to face, help me face it no matter how bad or painful it is." When I pray that prayer and review past pain in my life - I am able to face things, resolve things, and heal; it seems that life as I know it is actually different than I always believed it was and all these years I didn't understand or thought it was just me. After about 3.5 years of this (I had so much dysfunction in my life it takes me this long) I have begun to notice quite accidentally that my SA is getting better. It hasn't been the result of any one action but the support God gives me to face things, the counselor, and going to church where new topics about how to overcome things etc. are presented.
In the past month I have been 'able' to attend two events that I normally could never attend. One was the 18th birthday party of my friends daughter. Unfortunately my SA was so strong in the past that I had never attended the other 17 birthdays the girl had - but I got to go to the 18th and it wasn't hard (how strange!)- it was confusing to me because I couldn't figure out what was missing (hey-where is the sheer panic?) and I kept looking around wondering what was different and why attending this party would have been impossible all those years. I am not cured (I've only had two small wins) but the bonds are begining to come off and, while I had to struggle and grieve etc with God and through counseling, the actual going to the party portion was strangely ok. My faith is stronger and more honest now - I talk to God when I am hurt and angry and I let him know just how I feel - and I am healed. I still have farther to go but after decades of trying to overcome SA with zero improvement - these past few years have encouraged me so much.
