Does it sound like i might have a problem?!

i mostly feel all right but every couple of weeks i get really depressed just as a combination of all my negative emotions and lie in my bed and don't talk to anyone, sometimes cry. since two tuesdays ago as soon as i get home i slept and i'm really nervous and anxious to talk to my parents and hide whenever they come in my room. i can't talk to anyone in my family. it was my birthday and when my brother came down i just ignored him and ended up crying pretty hard when he left out of guilt. but i'm ok when i'm at school with my friends, i laugh and everything except that i get pissed off and i don't get excited. i just sit in my room and my parents have to bring me food on a ******* tray and i feel really guilty and shitty about it because what the **** do i have to be depressed about.Health Question & Answer
