Anxiety help

I was on Propecia for about 10 years, no noticeable side effects. Started having some bad headaches a few weeks ago likely unrelated but just decided to stop taking propecia cold turkey. It’s been about a week and half and I’ve started to feel really anxious over the last few days. Woke up almost every 2 hours the last 2 nights with my heart racing and feel tightness in my chest. Had a whole bunch of tests for headaches, and heart, blood work, blood pressure was all good but doctor said testosterone was low which I now assume must be related to the propecia. Going to see a specialist about the low testosterone. Does this anxiety sound like any withdrawal symptoms others have had?

Appreciate your help.
