random sadness

is it normal to just get totally sad/depressed/just want to roll up in a little ball in the corner and go to sleep totally randomly? like i've been getting that feeling a lot, and i have no idea why. right now i feel like that. i don't want to do anything, i just want to... um... blech. i don't want to do anything. i don't even really want to talk to my stalkee tomorrow (i would have talked to him today, but he was talking to his best friend every time i saw him).
anyway, maybe i have like a depression issue. should i go to the doctor? i don't want to go to the doctor! that means i have to get flu shots.
o and i'm scared i have breast cancer. is that possible in a 14 year old? maybe it just my boobs growing, but they have like a hard center with bumps on it. god i'm scared. that would be total shit if i had breast cancer at 14. i don't think that's possible, but i'm not going to look it up, just in case it is (that's right folks! i said i'm NOT going to look it up. denial rocks!)
