Does hypochondria(health anxiety) often start out of nowhere?i was never like this and then last month out of nowhere ive had thoughts of cancer & als

Acknowledge &; file: You can acknowledge these anxiety thoughts and say to yourself "OK. I am having them. Are they realistic?. Nope! . But they sure feel real. What if they happen in decades? Can I keep on working, loving, enjoying, learning for the decades then IF they ever or never arrive.?SURE! ". So give yourself permission to have these thoughts. Then file them away in a special place; and get on with life!
