I have selective mutism.
There are some people who I literally cannot talk to. Like nothing will come out.
Suffered with it really bad as a child. Everyone thought I was such a good girl because I didn't speak. Truth was I couldn't ######6 speak because of anxiety. It's funny because really talkative friendly girls and older kids sort of took me under their wings for some reason. Got into drugs and alcohol quite young but still didn't really make a sound. Even got locked up. Did probation for three years and never spoke to probation officer. He took it personal and got me another officer to see. Didn't speak to him either. I remember threatening to knife my social worker once in court when she had me put on a secure order. I've said so little in my life that I can actually remember most of what I've said.
Started using amphetamine in late teens and that's when I started talking more and I got ######6 hooked on the stuff just because it made me talk. Used to call it my lifeline. It was like a miracle cure for me. Took it for years and went absolutely insane with it.
I'm kind of quiet still but I push myself to talk. I can spend days without talking. Its funny how well I do work wise but that's survival.
