I lack of self-esteem isn't a failure but happens easily if people pick on you without a reason. It makes bullies feel better about themselves. Losers they are.

Without trying succeeding will be hard and if it doesn't work out you at least learned you should do it differently to make it happen.
It's normal if it takes time, it's normal the older we get the more we know and the stronger we are.

Great your mom and friend noticed your struggle and did put their faith in you.
Stay yourself, do what is good for you and you will be fine, a strong personality everyone envies.
