I can’t stop crying

I’m not normally like this. And I thought I didn’t have PPD but maybe I do? My daughter is 3 months and I THINK she could be going through the 4 month regression. She’s not sleeping well at night (waking 1-2 times where before she was sleeping 10-10 with 1 feeding at 6). She’s been really difficult to get down for naps- screams, arches her back. I try it all... wake windows, sound machine, dark room etc. she’s starting to roll on her side too so we have to slowly stop swaddling which is difficult.

But my husband also went back to work. So I’m doing all the night stuff. I’m just soooooo tired and exhausted!!!! I’ve cried so much today.. I hate it! I have a therapist for anxiety (had anxiety before pregnancy) and I might have to mention I think I have PPD but honestly it makes me feel ashamed even though I know so many women have it! But i just don’t know what to do. I get so stressed when my daughter is acting like that and I just want to put her down when she is screaming and leave the room but I can’t and would feel way too guilty. Ughhhhhh 😢 it makes me feel like a bad mama when I get so frustrated but I love her SO much!!!!
