Hate feeling this way

I am 7 weeks post partum and feel like a totally different person now that I’m a mom. I cry over everything, sometimes nothing, I’m worried all the time and have such bad anxiety. I feel like a bad mom when my baby is upset. I feel guilty and like a horrible mom for supplementing with formula occasionally and not exclusively breastfeeding even though I know it’s ok. When other people hold her I’m constantly there watching and can’t relax until she’s back in my arms. I don’t trust anyone with her. Sorry for venting I just hate feeling this way.
