How to feel better about myself?

ok, the fist thing you can do is tell yourself i'm beautiful in every way. Second of all if you really feel stupid and worthless prove to yourself your not. If your 14 im guessing ur in 8th or 9th grade, try getting honor roll or do extremely well on a test. Sometimes it also just helps to let it out. Write a letter to yourself explaining how you feel or maybe a poem or a song. And lastly i want to tell u that i dont even know u and i believe that ur NOT stupid NOT horrible NOT worthless NOT ugly. I hope i helped :)
