Greg,
I want to say that I see that you are in a lot of distress. That is perfectly normal at this stage in your recovery. You can and will get better if you continue to work towards it. I think most of us on here have been there. I've regretted things I've written, I've definitely regretted what I've felt or thought - and that is true of everyone I've ever met. It's normal. You can get through this.
In regards to your postings being deleted, if you have a moderating concern please PM me but we do not delete post unless they are personally identifying, I'm sorry.
I think by writing some of the things out here you are no longer able to dissociate away the parts of your memories that you do not want to or are ready to acknowledge. You've written several things that you no longer remember why you wrote (as you say yourself). If parts of you hold these feelings and memories and you write them down, you will be faced with them again and again. That can be difficult but it can also be a very positive thing: you are reminded of your amnesia. You don't have to walk around blindly. You have yourself and by keeping a record here (or anywhere) you are allowing yourself the clarity to remember what you felt later on. Journaling can be very healthy, as long as you do it in a way that you feel comfortable with.
I read your words, and I'm here if I can help.
