Postpartum depression?

My daughter is 10 months old. For the last few weeks I’ve been going through something. I’ll randomly just get really sad. I just feel like I’m not pretty enough, not skinny enough, nobody wants to be around me, I feel so alone, not good enough. It lasts a short time usually. I’ve been super emotional and can pretty cry at the drop of a dime. Getting agitated easily. Does this sound like PPD? Or something else?
