I have always been really shy. I thought I would have outgrown it by now as I'm in my mid 20s but it still really affects my life.
I have made lots of improvement. At work I can be quite chatty with my colleagues once I have gotten to know them. I can cope with doing things others with social anxiety would struggle with (ordering at restaurants, speaking on the phone, etc).
However, whenever I'm with anyone senior to me I really struggle. At work I really struggle speaking to my manager or anyone senior. I completely close up and just cannot talk beyond short one-worded answers. I also struggle with older family members (grandparents, aunties and uncles). I also really struggle during job interviews. I completely dissociate and have an out-of-body experience, my mind is completely disengaged from what I'm saying and I speak really, really quickly. I have just made the decision to cancel an upcoming job interview as I just couldn't bring myself to put myself through the stress of it all.
I feel embarrassed as I can see senior staff at work changing their approach when communicating with me. My manager is really nice but quite serious but when she talks to me she changes her tone, I think she's scared she will make me cry if she's too stern/serious. It also happened at university with lecturers. It feels like others feel that I need to be treated like a child and something about my shyness is making them act like that.
I don't know what I can do. I am out of my comfort zone a lot at work, constantly speaking up in meetings but it hasn't helped me yet.
