Feel this way

Sometimes i get this feeling and i don't know why, sometimes its like nothings right in my world of misery, sometimes its like I'm not there, walking though the halls, people just walk right by me like they don't give a care. why do i feel this way, i know its not true, if only they would show me that what i have proved is wrong, but will it help. my life has just started, but feels like the end. will my friends still have faith in me till the very end, i hope so and i hope that things will turn over again
