Postpartum depression

Has anyone developed symptoms of depression 8 months pp. I’m not even sure it’s PPD and maybe I’m just irritable and sad. Lately I’ve been super overwhelmed,frustrated with my husband and my babe. Like my bad attitude comes out and I regret it right after. I’ve never been a bold person with anyone. We currently have one car which my husband uses for work so I’m home all day. We’re also staying with my mil while our apartment is ready. So I’m in our room all day. Literally. I only go out if i need a bottle. Some days i dont eat until my husband comes home at 7 pm. I’m doing the same thing w my son, playing, feeding him, bathing him (normal stuff i did before) but i have noticed i get hot flashes and get irritable. Yesterday I got so frustrated my husband was on his game and threw a fit and literally locked myself in the bathroom and tried to cut my veins. Not my smartest moments. I feel worthless, not a good mom/wife. But I don’t want to kill myself. I just think about it and feel bad and cry and cry. I cry so much. My husband found me sitting in the bathroom and i told him I needed help and now we’re making an appointment with my Dr to see what’s going on with me.
