Hi, I've been going through a lot and I can't seem to find any answers from doctors, so I was curious to see if anyone else has gone through this?

So, around 4 months ago I decided to switch medications. I began tapering down from Pristiq 100mg and tapering up to Zoloft 200 mg. When I got to 200mg of Zoloft and 50 mg of Pristiq I began experiencing some weird side effects. I initially thought it was a sinus infection, but after a month of different antibiotics, a visit to two ENTs, multiple ER, and urgent care visits, doctors decided it wasn't a sinus infection. My ENT thought I was experiencing vestibular migraines, which made sense given my symptoms and history of migraines. I saw my neurologist and she finally realized that it was probably not vestibular migraines, but the Zoloft. 

Now, here are my symptoms. At 200mg a week in I began experiencing a tremor and I spoke with my psychiatrist and we agreed I should go back down to 150mg because that was the last dose where I didn't have a tremor. I also began experiencing a vertigo-like sensation. The closest way I can describe it is like I was sitting in a car bouncing along all day long. With this sensation, I couldn't look at screens without getting extremely nauseous. A week ago, I quickly tapered off Zoloft and my tremor has gone away. My anxiety is worse, but I expected that. However, this dizzy sensation has gotten a bit better and I have been able to tolerate screens for short periods of time without getting nauseous. But it’s still there and now I have the brain zaps, which honestly aren't bad and I can deal with. 

Anyway, it’s been months and I'm in my last semester of college. I have three classes left and I'm struggling because of the dizziness and the screens thing. I just don't know what to do. I'm not looking for a diagnosis, I just want to know if anyone else has experienced this? Am I some medical anomaly that no one can figure out? Any suggestions?
