I just came back to this forum thinking the same thing. Lately, I've been getting a lot better about my SA and being a little bit more social with people. I still have SA, but a part of me is terrified of not having social anxiety or shyness anymore. I'm scared that I won't be me anymore, like I've become someone else. This has been my "safe haven" for the longest time, so used to having it ever since forever.
If I ever become "normal," I'm afraid that the "old me" will die off and I really don't want to be somebody else. But yeah, this Social Anxiety that we all have is an limitation, like some other people said in the thread. At the same time, I know that I have to move past this anxiety, and become more happier and comfortable with who I am. Change is always scary, I guess some of us are just clinging on to something that we feel comfortable with.. could be one of the reasons why it's so hard to not be this way.
