Feeling guilty fur babies

I have 2 dogs and 3 cats. My fur babies are just like my own kids but recently both me and my SO have lost our jobs and now In financial hardship. I cannot take care of them. And today I noticed on of my cats has worms. So I have to assume the rest of the animals do too, also I’m having a hard time getting the fleas under control (I have a toddler at home and we’re all getting bit up). I have no family that would take care of them until we get back on our feet. I don’t want to surrender them as or shelters are full and will only end my babies being put down. I’m so overwhelmed idk what to do. I might be pregnant too so everything is just like ahhhhhh. Any advise please
