Prenatal depression bc of MIL

I’m pregnant and depression has been kicking my ass.

I have a wonderful life. A healthy 2 year old, amazing husband, I’m a stay at home mom, and now I’m pregnant with my son. However things are getting to me.

A couple months back my mother in law and I got into a argument because she kept insisting that my daughter is hers, that’s her child, and my love doesn’t compare to the love she has for my daughter. Now its been eating at me. I feel like my daughter deserves more. To have her grandma instead of me, because I’m more strict and I’m not all lovey dovey. I let my daughter do independent things such as feed herself, but my MIL will hand feed her like a 6 month old and baby her and I feel like maybe I’m not the best mother at all. Maybe I don’t love her as much as she does because I don’t do the things she does.

Another thing is my son.

Ive been afraid of her to be around my son as some things she has done with her son seem a little too inappropriate or me (talking about how big his penis is, slapping his ass, making out with his neck and face, always walking in when he is naked and showering, etc)

She never leaves me alone. She texts me day-night. Always asking what I ate to feed him how much water I drink for him, asking when my obgyn appointments are and wants to see him, same with my daughter.

“What did you feed her?”

“Is she behaving”

“How does she do on the potty today? Pee? Poo? How did it look”

“What is she doing”

And a whole lot more. If I don’t respond she keeps texting and tells my husband I’m distant. It’s going to get worse when baby gets here. I’m going to be up every 2 hours attending to him and taking care of a toddler and then having my phone go off non stop to see how the kids are.

She stresses me out to the max. I’m depressed my dr wants me to talk to someone and I just don’t know what to do. Talking to my husband isn’t a option as his mom is not ever wrong. No matter what she says. No matter how many times she tells him I’m using him, taking advantage of him, horrible mother for asking for his help. My kids are just better off without me and having her.
