Im here on and off listening/reading and posting. One thing that helps me is I just post my first thoughts. Sometimes I tick people off by my being too honest and up front by my posts but with the ones I've ticked off comes many more friends that have let me know how much they like and understand my thoughts, problems and posts. I used to be worried every time I posted on websites about making people mad or triggering then to the point where I wasn't posting and things just boiled up. So the way I finally balanced this problem of mine is that I ignore the voices telling me not to tell and that I am doing something wrong and I just post from the top of my head so to speak and leave it up to the moderators to let me know when I have stepped over the lines of rules because that is what they are in those jobs for. If you don't recieve a pm from the mods then you are doing great according to the rules of the place and what I personally can see --

You are doing great.

So take a deep breath and let your fingers go typing all those thoughts howver they come out. It gets easier each time.
