Is it normal to have a migraine last over 2 weeks? I’m spiraling

I haven’t had a migraine since 2017, then 2 months ago i started to taper off of zoloft. Since Christmas I’ve been having light and sound sensitivity, feeling off balance, derealization, neck and jaw pain. My family doctor said I just had covid but I’m 99.9% sure it’s not covid, I had it before and the symptoms were different. I”m just anxious and unsettled that I still have symptoms for a little over 2 weeks. Any advice appreciated.
