Sometimes I think the Internet is both a blessing and a curse! I always look up symptoms on the net, too. And more often than not, you always find the worse case scenarios listed. It's never just a migraine headache, it's a stroke. It's never a bump on the arm, it's cancer. It's never anxiety making your heart race, it's heart disease. On and on and on! I am a hypchondriac also and I am trying REALLY hard to stop looking up symptoms on the Internet. I know it's hard, but trust me - it helps to not follow that urge and google every twinge that comes up! I still find myself pulling up the Internet when one of my kids, my husband, or I have a symptom but I try to remind myself that not everything is worse case scenario and I usually close the window rather than look it up. I tell myself, if it's something that doesn't go away or gets worse, I can always call my doctor and get an accurate diagnosis rather than let my imagination run away with me. I know that's so hard to do, but it does help. I still struggle with this from time to time, but I keep working on it.
On the other hand, if it wasn't for the Internet we wouldn't have found this website to help us get through this nightmare! ;)
