hope and expectation

BIG SIGH.
i hate feeling like this.. so shitttyy:[ i have homework and i reallly don't wana do it but grades are slipping. aii what is wrong with meee? ajsfafd; UGH.
well anywaysss this mood got me all thinking about buncha stuff. i guess in a way i feel shitty and just down on myself cause i think i have such high hopes and high expectations and those just gets crushed. Having high hope is good but when whatever you hope for doesn't come true it just bites you in the ass and you just get dissappointed. Same goes for expectations. i don't think anyone could live up to my expectations so i might as well just stop.. stop expecting soo much cause it won't do me any good. All these things i hope for.. i don't see the point anymore, my hope for things is slowly dying. i mean i still hope but if gets to the point where everything just doesn't go right.. imma lose my hope. all i want to do now is cry, cry my freaking heart out but that won't help so i'm just keeping it in. i'm tired of crying anyways, it doesn't do any good cept make your eyes all puffy. god! i am so down right now:[ which causes me to think negative and beat myself up over stupid things..
why can't i get what i want?
