Usually I only need to take a Xanax (.25mg) or sometimes two during a bad panic attack a few times a year. Unfortunately I got COVID about 3 weeks ago and it set off an anxiety chain reaction due to symptoms causing anxiety and anxiety then causing more symptoms. Anyway, during this time I was taking Xanax daily between 0.75mg and 1.50mg depending on how I was feeling and also to help with sleep.   


It has been about three days since I stopped taking any Xanax and I feel like I'm extra fatigued, my anxiety is heightened, and just an overall "blah" feeling. Could this be from taking Xanax for such a short amount of time and then stopping? Or is that much too soon to develop dependency?
