Glad I could help! HA is a symptom of OCD usually, and how OCD usually works is Anxiety/Doubt/Uncertainty pop up ---> You engage in repetitive checking/reassurance behaviors to feel better ---> You begin obsessing about the issue. It seems counterintuitive as you might think that obsessions fuel compulsive checking/reassurance, but its actually those checking/reassurance behaviors that fuel the obsessive thoughts. Stop the behaviors, the thoughts will fade on their own.
When anxiety like this comes up, it is best to sit with it for a while and not do anything about it. This will seem so odd and alien to you, but after a while, you'll realize that your need to know and your need for reassurance is what is making you so miserable.
It really helps to recognize that reassurance will not really help you feel better, as much as it might seem that way.
Highly recommend watching Mark Freeman's OCD videos on YouTube. Whether you have OCD or not, the advice is universally helpful for anxiety of any kind. They are really simple and generally short, focused videos. Finding a therapist to help you deal with it is also a great step!
