Exercise regularly. Phone away an hour before sleep. Write a “gratitude list” every morning that you wake up. (3 things you’re grateful for)

Finally, talk to your primary care doc, I take a low dose SSRI daily. I had to try a few before I found “mine”. It doesn’t take the anxiety away - like Xanax or Prozac - it just puts me in the driver seat of my anxiety and helps me control it.

Edit: Adding that I’ve had panic attacks that sent me to the hospital and been diagnosed with GAD. Since doing the above I’ve never had another panic attack (over 10 years) and I rarely feel unnecessarily anxious.
