I Dont Know What This Means But Im Extremly Worried :'[

about a couple weeks ago i was with my boyfriend

and he started to give me a hickey when he freaked out

because the area he did it on started bleeding alot

& he rly didnt do it that hard so i got worried too cuz that never happend before

it worried me so much that i couldnt stop thinking about/couldnt sleep

so the next day im like i gotta see if it happens again

well i cant rly do it to my own neck so i tried it lightly on my arm and sure enough it started bleeding but i noticed it stopped right after and there was no brusing and no open cut it just seeps through the skin and then goes away

i asked this question on yahoo answers and all i basically got was a bunch of rude people making fun of me so hopefully someone has an idea of what this condition could be and can be kind enough to ease my worrying
until my next doctor appointment a couple a weeks from now

also sorry if this dosnt rly qualify as a question for skin cancer its the closet thing i could find that was related to my issue
