Almost 1 year, still struggling

Am I the only one? SAHM to an almost 1 year old. Partner works constantly, no friends or family nearby.

I am still struggling to do this whole mom/homemaker thing. When I ask how people how they do it they say "I just do" which doesn't help because I am very much trying to do it. I feel so mentally drained that I can't even play enthusiastically with my baby. I think that's more because of no breaks.

I clean when baby naps, but even then not much gets done. I try to cook but baby is constantly on my feet once I'm in the kitchen. Last time I tried, dinner was burnt and inedible. So I never really eat (baby is fed and put first though).

I feel like I'm always on the verge of crying. Everyone always says the earlier months are the hardest but it never seems to get any easier. Has anyone been through this? How did you get through it? Am I just too stupid to be a mom? I love my child, just not motherhood I guess.
