i so have this too, all the time. sometimes my fear on one thing will calm down, only because i have a fear of something else. i am very obsessive compulsive, and i can't stand it. i worry all the time about what if i have this, or that............... my boyfriend laughs at me, and makes jokes about the things i worry about, which i don't find funny, because the thoughts scare me so much. Any little thing that i notice on my body, etc, or how i feel, i look up on the internet, which scares me even more, because it states 'that could be a sign of...........' i have been like this for as long as i can remember, but especially the past year. the past year has been so draining with all this garbage, i wish i could just stop worrying and carry on with my life. it's so hard. even if i go to the doctor's about something i think is wrong with me, i think that maybe the doctor doesn't know and i'ts serious even though they say it's nothing. that's my ocd coming out when that happens though, and i try to tell myself that, but it doesn't work.
