what can be wrong with me please help

Hey so I started having blurry vision where my vision would unfocus and become blurry 1 year ago since I started wellbutrin, 6 months ago at least I went off it and my vision improved but not fully resolved, 3 months ago I caught flu/covid and since then my vision problems became severe, my vision unfocus every 1 second to the point I feel half blind, I went to a eye doctor which didn't do a eye test with dialate drops since I already had one 7 months ago but did the basics without dialation and sent me to do oct test which I am doing tommorow, I am really scared that I am going blind and dont know what going on.
