No one cares

Have to vent a little, get this off my chest cause I honestly feel so alone.

I've just had a baby, she's beautiful & i love her in every way possible, I'd do anything for her. But I feel like everyone would be better off without me. I feel like I'm doing everything wrong. My body is horrible, I'm forever in pjs with my hair scraped up looking like shit. I'm terribly insecure about the way I look. No one will help me, and when they do I feel as though they're judging me. I do all the night feeds, bum changes & it's making me feel like throwing myself in front of a bus. I love my partner and daughter to bits but I feel as though they'd be so much better off without me. My partner doesn't see his other son because of his mother cutting contact since he got with me. I feel like I've ruined his life. I don't want to feel like this any more.
