birth control patch week 3 very very emotional + other side effects

On week 3 of the birth control patch evra i get really emotional like a PMS week but worse - is that normal / will it go away?

I also thought it was supposed to suppress sexual desire but I’ve been on mine since December and it feels significantly worse actually.

Lastly can someone explain to me like how back to back cycling works - can I just stay on the patch forever?
