Postpartum depression

I just got diagnosed with postpartum depression a few days ago, and my emotions have been all over the place lately.. I just don’t know how to handle it. On top of that my baby is teething right now so she’s really fussy and I’m the the only one that has to deal with it, literally 24/7, just me. So I’m severely stressed right now, and I called my husband upset and a little angry and he snapped at me and said “and you wonder why no one else cares about you” and threatened to hang up on me. I don’t know what to do, I just feel so alone and now humiliated by my own husband:(
