So I’m not on the pill but curious

I’m not on the pill or any type of B.C. I haven’t had too many periods because of some eating disorders and mental health issues so I’m not sure about very many things. When I’m on my period It makes me just want to go back to the bad days of eating issues, I get super moody, almost suicidal sometimes.

Just a few questions:

1. Will taking the pill help balance my moods?

2. Will taking B.C. Help with eating and help with bad body image??

My period/week before period is like a 1-2 week period of how I was when I didn’t eat and had depression and stuff
