Emotional or consult about PPD?

I feel bummed out writing this. I have a 14month old and a 9week old. I feel so alone-I have no friends- I have one who doesn’t have kids and has a career. It’s winter where I live so we don’t get out. My husband got a promotion at work and has about 3 late days a week where im by myself until 10pm. I feel like my life REVOLVES around the kids. I make myself get out of the house to the grocery store or Target to walk around. We have dogs that I basically despise now that #2 is here. My husband helps when he’s home and he doesn’t bug me about the house being dirty but I can tell it being messy bugs him. He comes home and will start cleaning up and he says it’s just to help and I really just want help with the baby and have a break. The baby is EBF. I’ve resorted to co sleeping. My husband and I haven’t slept in the same bed in 2 months and have had sex multiple times so I’m not really worried about that. We bicker about everything it seems, and we’re both so tired I’m just in this rut.

To make matters worse, I messaged an ex bf from 6 years ago about smthing innocent and we had a small convo which now caused my husband to question our relationship (my own fault- not blaming my emotions on this, as the ones I’m describing were there before)

I feel lonely at home, and don’t feel like I have a purpose other than kids. I have no hobby, I have no family nearby, besides his mom which has helped on numerous occasions, no friends, I’m not sure if this really is an emotional time and I’m under stress or I should actually talk to my dr about PPD. I’m not one to take meds and never have- I’m reluctant.

I feel like im just stressed and overwhelmed but I don’t want to be naive. I don’t know anyone that has had PPD and have no one else to ask.
