Hey Tim
Plucking up the courage to make your first post is a big thing. I did the same. I read here for about 12months before I posted for the first time. And like ShadowGX & Skeezys have said there is no need to do anything more than you're comfortable with. I have always found the community here to be friendly, understanding & helpful. I'll be honest I find a lot of help & comfort in reading other member's posts & the replies.
Take your time. Do what feels right for you. Take good care of yourself
