I was like u too but then I made a promise to my self that I will work hard on my confidence. What I did was I started to get to know my self love my self really know my self... cuz once u know who u really are the game changes. Accepting ur self is very important. It doesn't happen over night u gotta work on it but eventually u will get there. And finally having a good outlook on life and also about ur self. Feel ur self with positive vibes, and let go of the negative thoughts that tell you you cant do sth. I hope this helps u
