butterflyexperience I am so sorry to hear about your experiences and I really hope you can find peace. I believe that Jesus can give you that peace. I know it is not easy and sometimes things happen quickly, sometimes not. I agree with what jan2011 has written above.
Religion is not perfect but Jesus is! churches are full of imperfect people but I do believe Jesus is perfect and I think asking Jesus if he is real to reveal himself to you in a loving way, to give you some peace and lead you, would be a really good start.
Churches are funny old places, some are groups of people meeting in old ancient buildings, some are groups of people meeting in schools. They are ordinary people and they are not perfect, however they are made up of people who have encountered God, and also people who are searching for him. If you feel able to join in the search you may wish to visit a church locally and join in on a Sunday service, an enquirers service, or some other type of meeting/event where you can find out more. If (as we are on mumsnet!) you have young children you may find they have a group for mums/parents/kids, if you are at home during the day or the evening etc they may have a small group that meets at a time that can be convenient for you.
When choosing which to visit, if you wish to visit one, I would just find out a bit of info and see what you think. Most have websites now so you can get an idea of what they do/when they meet.
Personally, I greatly enjoyed doing an alpha course in my thirties, I was already a Christian but I have heard of many others who have become Christians through doing an Alpha course (which is a weekly evening course of chatting sessions around a talk given by someone in the church BUT don't feel I am suggesting this straight off, I am just telling you what I enjoyed!). If you want to find a church that is a bit vibrant, lively, outward looking etc it can be useful to see whether they run an Alpha course (or have a while ago) or what else they offer for enquirers etc.
I don't suggest that this will answer all your questions and at the end of the day meeting with God personally is the really key thing to finding healing (i believe, in my humble opinion) and hopefully churches have people in them who are also on this journey of life and are also looking to walk alongside God.
Having suffered anxiety attacks in the past and having got help through CBT (Cognitive behavioural therapy) I am a big fan of talking to people when things need help, and counselling for me was wonderful when I had my anxiety. No idea if counselling would also help you with any issues and with finding resoluton for some things. I don't think it is either or, I mean I found counselling helpful but I also asked for prayer when I experienced my anxiety attacks many years ago.
PHEW long reply, sorry to go on, I really wish you every blessing on your journey.
