How can I raise my self-confidence?

You look completely normal and nice looking in the picture to me. The best things to do to boost your self confidence would have to be coming up with things you LIKE about how you look in the mirror, finding hobbies and things you're good at, SMILING!, and realizing that there's only one you in this entire world. The people who can't appreciate you for who you are aren't worth your time! You're unique and beautiful inside and out. Learn to embrace how you look.
