How do I improve my self esteem?

try not to think of yourself in that way.. i know its hard on yourself ive had that feeling before like if know one liked me even though i did have some desent know crushes but well even that didnt help me.. but u know what i learned is that u have to learn how to care about urself first then what other people think about u or how many girlfriends have other guys had..i had my first boyfriend after the age of 18.. i was somewhat upset cuz well i didnt have one in high school but then later u understand that in life theres a grater outcome and by time u might meet someone thats well going to share the same interest..whatever i did i did it for myself.. i started doing a hobby and trying to keep myself busy without no friends around..cheer up and take day by day a step further in being a stronger person from the inside.
