How do you know if you have postpartum depression ?

Cali☀️

I have this what I think is a pinched nerve in my neck but it’s been 4 days and won’t go away. I’m on 800mg ibuprofen which helps but if it wears off my pain level is at a 10 and I can’t do absolutely anything. I have a 1 year old and a 2 week old. When I am in pain there is absolutely no way I can take care of two babies by myself. Anyway, my point is I am angry and upset because this pinched nerve thing is really the last thing I need. When my babies are acting up I get angry and upset and believe I might have postpartum depression. The dr said my “pinched nerve/muscle spasm” can last 4-6 weeks which I really don’t have time for that. And masking it with pain meds isn’t solving the problem but he told me there’s really nothing I can do smh. I went to the chiropractor for the first time but that didn’t help either. I was up all night in tears because of the pain and I feel I’m just not physically and mentally stable😣
