how to deal with health anxiety / being a hypochondriac

hello people of 7cups! i recently found this website (as in an hour of posting this thread) looking for a way to vent about my health anxiety. i often post on reddit, but my posts are usually lost in the sea of others and wanted to look for a more engaing community.

i personally get super worried whenever i feel the slighest aches in my body and my anxiety has made be go to the ER and doctor's so often in these past 3 months, which has never happened before. even recieving reassurance from doctors (results would always come back normal), some new thing seems to be going on with my body and i go into full panic mode and think of the worse. it's affected my concentration pretty badly and also puts stress with my parents as well.

i was wondering how do you guys deal with health anxiety/being a hypochondriac and get past any health concerns that you may have even after getting reassurance from a professional?
