I feel so alone even tho I’m married

I feel like I’m struggling as a mother. My second oldest son just said that I’m not his mother even tho he knows I am. I texted my husband about it and he just says I can’t help it. And I feel like that’s the response I always get. I feel so alone doing this parenting by myself and feeling like I’m only a doormat to my husband. I don’t know ladies I’m in my feelings. I’m trying to get out of depression so bad and I’m even on my meds. I feel so so alone and I don’t know how to change it.
