Plea from a newcomer. in Here we go.

So I have a lot on my mind right now (as always), so I thought I would try something new. I have journaled in private and attended therapy off and on the majority of my adult life, but I have always steered clear of anything online. Even typing these sentences is hard for me so here is my simple plea; if any members have any tips, topics, or general advice for someone totally new to this whole thing, I would greatly appreciate it.
