Lack of friends, not being in the cool crowd, not being good at sports, a girl or boy doesnt like you, not having the nicest clothing, pimples, etc.
I had em all but didnt get down. Its all good now. I understand that we were all geeks when we were young.
Peace

could be many reasons wish I knew but I know many teens who are depressed and I am 60 years old. with many it is idle time , nothing to do therefor no accomplishments no feeling of self worth. but you are worth much keep that in mind.

having lived in the 50s as a child growing up the amount of knowledge and information my brain was exposed to is 100 times less that a person is today .too much negative info can cause depression .also too much is made about a few who have extra talents extra smart extra good looking .those people tend to have a downer effect . makes one freel what happened to me? why am i not like them . and worrying much.so if i am speak about you quit it. you much better off than people that lived in the past.
