Breaks are good, yes.
Then, just take a chance when you feel like it and post. This website doesn't require perfect communication for participation. Sometimes it's taken me hours and still isn't understood by others.
One thing that really helped me is when I had trouble wording and tried and see what other people say, another thing that helps is just reading and not worrying about responding. And it's also really helped to write and ask if I made sense, and when the answer was no, sometimes someone else jumps in to interpret and it's a relief not having to try to do it, not having to struggle. People here will do that sometimes, it's nice just to be able to try to communicate in words but not so hard it hurts, and then say I've done my best, let whatever happens happen. The real world isn't so understanding, but people don't really seem to make fun of problems communicating much at WrongPlanet, nor demand trying so hard it hurts like they're entitled to great communication from others as a fundamental entitlement. Just knowing that reduces my anxiety about communicating some which makes it easier.
Does this make some sense?
