I wouldn't really call what I have Social Anxiety. I prefer the term RFMA (Reasonable Fear of Murder Apes). What I am is severely ****ed up.
I have one friend who lives in a different town that I talk to about 2 or 3 times a year and one online friend that I talk to several times a week.
I spend almost all of my time alone in my room. I push myself to do as much work as I can, writing, editing, and researching, because I can't work with the public, I can't get disability, and my family won't support me. I live in constant dread of being homeless, but I might be able to put it off for a year or two. I'm hoping therapy will help.
said, we're not all here for the same reason. I've never been particularly concerned about what people think of me, or embarrassing myself, and I don't have poor self-esteem or a particularly negative self-concept. These seem to be common problems for many of the users here. I would never avoid talking to someone simply because I'm afraid they might think I'm weird or because they might reject me. I'm not particularly bothered by the fact that people see me as "non-contributing" so I don't really care if they know that I don't have a regular job or that I'm poor because I have MH issues. Excruciating sensitivity to other people's opinions seems like a SAD thing, and I doubt I'm more sensitive than most people. I will just tell people that I have an anxiety disorder, that I'm too afraid to do something because of my anxiety, etc. I'm pretty open about all of that. But I won't go into details with them because...
What I'm afraid of is being murdered by random strangers, or not being able to stop myself from murdering them. That's my "violence-related pure O OCD with occasional poor insight" at work. The end result is that I generally only feel safe when I'm inside my room by myself, but it's for different reasons than most people here and to most people it probably looks like SA. I obviously don't go around telling people IRL that I don't want to talk to other people because I'm afraid I'll murder them. That kind of thing tends not to go down well. I've never told anyone in my family that, or my IRL friends. Only my therapist, my online friend, and people here know I have that problem. I can't really think of a better way to Lose Friends and Horrify People than to admit something like that, and I don't want people to be scared of me.
Ftr, I have never hurt anyone IRL. I'm about as dangerous as a chinchilla. But when I have an episode I'm convinced that I'm going to rip through people like a xenomorph. It can be thrilling at times, though. I won't lie, I never get bored. But it is kind of a living hell.
