I'm 22. I have a problem with making decisions, I'm never sure about anything I decide. I also feel like I lack an overall sense of identity, I can't tell what my "core values" would be, I don't have a personal style or anything like this and it all makes me really self-conscious in social situations. I'm never confident and I always doubt if I look good and if whether the way I walk and act or the things that I say are "right". it really makes everyday life for me hard. I cope by pretty much always copying the surrounding's behaviors and I rarely have arguments with people when I disagree with them.
I recently asked my friends if they had a specified path chosen for life and all of them gave me a more or less "yes" answer. I don't have such things figured out, but I feel like I should. My friends also have specific ways that they act, they have some sort of "values" they always obey and they basically know what's best for them.
My question is: how do I acheive this level of self-confidence? How do I develop my own personality? Is it possible that I have a condition that makes me feel this way?
EDIT. Some people will tell me to give myself more time to figure things out. The problem is, that the way I live won't figure itself out the way I live it. I want straight up advice on how to develop myself
