I'm on the verge of a total mental breakdown and I really don't know what to do. I'm on day 5 of being sick, like REALLY sick. Can't even function enough to take a shower

I finally made a Drs appt for today because I woke up hacking and wheezing and couldn't catch my breath.
On top of this my husband left for work at 9pm last night and still isn't home, it's almost noon. He'll get home and sleep until he has to leave, and do it all over again.
The dogs are running around like crazy because given, they haven't been out in 5 days. They get into stuff while I'm passed out in a coma. They house is trashed, and well, basically, I don't know what I'm going to do. I don't have any relatives out here to help and I feel so alone.
