Bizarre severe symptoms - are they related to Gianvi?

Hi,
I'm currently almost unable to function due to emotional problems, insomnia, and severe neck and jaw pain. BRAIN FOG is the absolute worst. I'm 23 yrs old. I started on Yaz but was quickly switched to Gianvi and have been taking that for about 4 yrs now. I didn't think starting BC was a big deal so I didn't connect it to any side effects (in other words I wasn't really paying attention!) But if I recall correctly, they did all start around the same time, and very abruptly.

I've been off Gianvi for a month now, and it seems my emotional symptoms have gotten worse after stopping it. Could I be having a rebound effect or something? This is just insane...

Has anyone heard of Gianvi causing sudden-onset:

- insomnia
- RIGHT SIDED neck and jaw pain
- anxiety
- confusion (it feels like I cannot solve any "problems" in my life , so they just go round and round in my head and I get a sense of confusion that never goes away...)
- BRAIN FOG! (I seriously go into fits of zoning out that I feel I can't control, especially when driving for some reason. I feel like a person all the time because I can't think of right words, etc. )

Please help!
