Panic Attacks and Infertility

I’ve never been one to suffer from anxiety, nervousness, panic attacks, or anything the like, until very recently. It seems to coincide with the start of fertility medication a couple months ago. Like everyone likes to remind you during TTC, “don’t stress,” and it’s much, much easier said than done. I don’t think I’m stressing about it til I’m lying in bed at night with my heart pounding out of my chest and battling insomnia. What have you found to help your anxiety and restlessness? For the record, I don’t smoke or drink and don’t plan on it - bad family history there.
