You say your mother speaks up for you, because I work at Chipotles serving people I have seen this a couple of times. I don't specifically know your situation but I wouldn't think that is good for you that your mother controls your conversation. I remember seeing a teenager girl walk in with her mother an dher mother spoke for her and when the girl spoke up her mother got all pissy. That's not good. Obviously the problem lies within the context of the mother, in this case, not allowing the daughter to gain any sort of confidence through her own actions. I'm kind of jumping out early here with my assumptions, but if anyone has this problem in their lives, it will benefit you greatly to serperate yourself from that source.I definitely think a large part of mine is genetic, or at least brought on by family members.
My family is very critical and nothing is ever good enough for them. Plus they make fun of me. I've asked them to stop a number of times and it's always like "we make fun of ourselves so we can make fun of you too". And it never does stop. :no My mom also listens to phone conversations I make and stuff, takes it upon herself to speak for me in public, and is always trying to set me up with someone, so yeah I know where a big part of my lack of self esteem and anxieties come from.
I know living at home is the worst thing for me and I have been really thinking about finally leaving... I think a lot of my SA would go away if I was away from my family.
