We can conquer this HA, by reading the recovery posts, and sorting out our plan. As cpe1978 says, you can become despondant, and think it can't be overcome, when you read the reassurance seeking posts. I think I have posted twice seeking reassurance, and it doesn't help in the long run. I don't answer the reassurance posts very often, because reading them sometimes brings me down.

My plan is this , if you are interested

No googling health worries.
Writing down my worries
Relaxation/meditation
Walking dog
Trying to eat a balanced diet
Spending time with family and friends
Learning to live with uncertainty (difficult but not impossible)

Saying to myself every day, I can overcome this, health anxiety is not in charge I am. I choose whats good for me not health anxiety or anyone else.

Whats your plan?
