Hormonal changes?!?!?!

I had a baby 10 months ago and I'm breastfeeding, I started my cycle back about 3 months ago. I have had huge emotional surges. I'm on a emotional roller coaster. I am not on any kinds of BC becuase any that I've tired makes me super emotional and depressed (plus I don't like it for personal reasons) 
So the question; is it normal to have these emotional issues becuase of breastfeeding and having a cycle at the same time? Are there ways to help?? 
So tired of feeling anxious, sad, or "cold".
