8 months PP depression

So I think I might have post partum depression. I’ve been iffy about it since my daughter was born but in the last month or so I feel angry and agitated A LOT, I cry all the time, I feel like I genuinely hate my husband, and it takes all I’ve got to not yell at the baby (usually at night when she wakes up 300 times). I have terrible insomnia and I’m just so damn tired. Part of me thinks well maybe it’s all just from being exhausted, stressed and bc I get no help from my husband. But Incas it’s not I think I should see a doctor. All the being said, do I go to my primary care dr or my obgyn? What else can I do to try to make things better???
