eyes sore... headache

have been cryin for the past few days.. just feel so tired, drained and..... there r so much to do.. to think .. sometimes i start to ponder if i am really cut up for all these.. y do i feel so tired.. it it cos i take things too hard.. or do i want to please everyone too much till i forget abt myself.. how i wish i cld hide into sth really small and be away from this world for a while. just have a moment for myself. really feel like puttin everything down and escape into my own world for a while.. just a while..
