Has anyone else had this?

When I was younger I would get obsessed over a lot of things, mostly about death and I can't shake it. It had seemed as though everything was fine for the past 8-9 years other than thinking a LOT about bad events and worrying about them. Everytime I think about one, I go online, which I enjoy and it takes my mind away from it for a couple of minutes. For the past month I can not stop the feeling that I have a particular serious disease. I have had blood work done and everything is fine but I keep having night sweats (a symptom) and I'm losing weight (another symptom)...but I'm not eating and its hot in my apartment. I keep looking at my skin for changes constantly. I don't know what is going on...I can't shake the feeling that something is wrong... I have had many opinions. They all say I'm healthy. What is this? I don't do this frequently, so it's not like I'm a hypochondriac. For the past month though I don't worry about death, just disease...a plus! Anyone else have this?

You have anxiety. Talk to a Dr. about it. There are medicines that can help you.

research Obsessive-Compulsive Disorder, you may learn quite abit about yourself.

Sounds like you are probably causing your own physical problems and just need to relax and forget about it. If you worry too much about health, you can ruin it.
