Feeling down after early miscarriage

Katie
I had an early miscarriage on March 7, and here it is a month later, and I feel like CRAP. I am exhausted, I have gained 6 lbs, and I have been weepy and anxious for weeks. I just confirmed I'm not pregnant, but I don't know why I feel so gross and low.
Did anyone else have this after an mc? I'm fatter than I've been in years despite no change in my diet and exercise, and have no energy. Could it just be mental? Would appreciate insight from anyone who's been through this 😢
