Hi Ronin, WELCOME to PC!!
I'm sure you're going to find plenty of people on here who can identify/empathise with the way you're feeling and there are a lot of really supportive people on here too. It's a great community.
So don't worry about how to post just make a thread (like this one) about however/whatever you're feeling, it matters!! Unless you want to get a bit more familiar with the site first, in which case just have a look around, make yourself at home, and hang with us until you're ready to talk a bit more about what's going on for you.
