Mood swings

Recently, I’ve been taking the pill again after being off of it for about 8 months. If it matters, I use Junel FE 1/20. Anyway, I don’t remember my mood swings being this drastic last time I started birth control. It feels that every other day I’m in a depressed mood. I binge like never before (I’ve gained weight too) and I’m snapping at everyone for really no good reason. Granted, I’ve been on the pill for a month, but I’m curious to know if anyone else has had this problem, if it will subside/get worse, and how to handle it... any advice?
