sometimes i feel like im just waiting for something bad to happen.
like my emotions will be good
and im very productive and feel good about my self for a long time
(like a few weeks),

and then out of no where, there i am
upset about nothing and everything all at once.
and it will just last for weeks at a time (sometimes longer)

it realy stresses me out not understanding why this happens.
or when it will happen again.

it has a big impact on my relationship with my boyfrienad
and on the ammount of work i get done (not to menssion the quality) at school.
it puts strain on all my relationships with those arround me too.

i just want to know if anyone else feels like this?
do you ever feel like you are just waiting for something bad to happen?
