Well, that's alright. I used to feel nervous and paranoid when I first started buying from there so I can definitely understand why you would feel that way.
Sorry to hear you're going through that, it does seem like it's causing you distress so hopefully it gets better soon.
For me today has been alright, I got some more heroin so I'm feeling much better now. Last week I had purchased a new drawing tablet for my PC, at first I regret it because it was an impulse purchase and I hadn't drawn in so long because depression completely killed my ability to enjoy it so I thought I wasn't going to be as good as I used to, but I decided to test the tablet out by doing a quick drawing of one of my favorite characters from a video game and I was pleasantly surprised to find that my skill level hasn't really declined at all. It really does disturb me just how badly depression can suck the enjoyment out of things I love to do though...
