Sudden outbursts and mental breakdowns

I’m 7 months postpartum and haven’t really had any issues with postpartum depression, but I do have instances of postpartum rage which I am embarrassed about, and have had anxiety in the past and have mild OCD. (Have been to therapy and medication for both)

I try so hard to be patient and go with the flow, but sometimes the lack of a consistent schedule triggers my anxiety and OCD. But I push it down and continue on with my day.

3 times in the last 7 months, all of the little triggers just built up until I have this huge, sudden mental breakdown. I hyperventilate cry for literally no reason at all and make a huge fool of myself.

It’s always when my husband is home and he gets genuinely worried about me when it happens. He takes baby out for a walk so I can be alone and just cry. (He’s a literal saint for dealing with me)

As soon as I get it all out and cry for a good hour, I feel so much better, like a weight is off me.

But then I look back at how I acted and feel embarrassed that I was so over the top about everything.

I wonder if it’s a combination of postpartum hormones and the very strong birth control I’m on.

Anyone else deal with sudden outbursts and mental breakdowns postpartum? Or am I just a crazy person?
