I cant anymore

I cant. I really cant my partners mother took a vacation which i thought was gonna be less than a week nope two weeks and I’m stuck watching a senior dog with high anxiety who poops out of spite barks a lot and growls at you for eating. Then theres a 13-15 weeks old stray puppy who is not trained pees on everything bites everything gets into everything every single thing. I might sound like im annoying about this sure but im 30 weeks pregnant ive been informed not to go into high stress levels due to being a high risk and my partners sister is out with his other sister ensuring the last of her pregnancy is stress free. Im sorry i might sound selfish but what?! Were both so close together in pregnancies. My partner works a lot of hours as well so I basically have no help on top of that my baby is going for adoption because my partner told me i would be a horrible mother for being selfish about not wanting to go through with the adoption and for my past (mental history with depression and anxiety) I have no one nearby and I’m alone most of the day. I get asked “can you make some dinner” as if im not trying to keep both dogs from defecating or urinating on the furniture or being electrocuted. Ive gotten a total of 9 hours of sleep in the past three ish days I cant im honestly so done with everything. I’m expected to go to a baby shower in a few days for my partners sister and i have to hide that I’m pregnant. Im so tired and done with life at this point.
