Normal is overrated. Nobody is normal, to be honest, that person you think has it all together has his own fucked up radio station in his head broadcasting fucked up messages.
I guess the quick and useless response is to question the thought... I avoid new things because of how my dad would take things from me and do them rather than encouraging me to learn to do them. I still struggle with this. But the response I have to that anxiety/shame is "well, why not? What's the worst that could happen? If people are going to find out what a charlatan I am, that's a judgement that maybe they don't even have." Also, never having learned how to fail prevents me from learning how to succeed, so my rational side says failure is part of the process. I have to give myself permission to fail or I won't learn anything new. That's how I address, for instance, self shame, the one truly useless emotion that I am told is worth rejecting (as opposed to accepting as part of myself).
