welcome to AS. Although all of us here can relate to your fear, there's no need to be scared. This is a warm and wonderfull place. I've only been a member for about 1,5 months, and I am still a little scared sometimes. But it gets better... this place is filled with wonderfull people who share similar scars and fear, and therefor you will find tons and tons of support and understanding here, without any judgement.
As for struggling with other post, that too is very normal I think. I am very selective to what I read. I try to stay away from the "my story" forum for example, because it is still too hard for me to cope with all that. I have posted regularly here, but I still have yet to say a single word of what has happened to me...
Just take your time, read and post when you are ready.. when you are, we will be here to listen and support you.
I'm sorry something has happened to you that makes a place like this necessairy... but I am glad you found it and I hope it will be a great source of support for you on your journey.
Take good care
ps. post that may trigger usually have a warning *T*. This can help you to decide whether or not to read them.
