Tips for hiring a nanny at home

I feel exhausted, scared, lonely, and just not in a good mental state. I don’t work a normal job anymore I’m a stay at home nanny for 3 children(way harder than it sounds). We live in the woods so I don’t walk outside (it’s a lot of loose dogs). I no longer enjoy watching tv or writing (things that calm me). Everyday there is a new pain. I feel like my body isn’t mine’s anymore. I haven’t been sleeping at night but exhausted during the day. Feeling like I don’t know what to do with myself. The only small joy I get is when my baby moves.My baby father and I are trying are hardest to be in each other’s life but sometimes we don’t feel connected. Mental Health problems run in my family so I want to take control of this before i feel insane. Every time I open up to someone they say that’s pregnancy ??‍♀️ is it ? When am I going to feel better? Is Ppd going to make me feel worse? Who else feels this way??
