What to do ?

What yo do when you have to live with your husband and two kids sleeping in one bedroom of your in laws house? When there are 4 noisy dogs total (one yours) and you are helping take care of a senior man with Alzheimer's that pees and poops anywhere... in himself, in the house, the chairs, sofas, etc and the situation is so frustrating that you don't even feel  comfortable letting your baby crawl in the house floor.
​you are forced to take in a way of living and doing things you are not used to. People telling you what to do and how to feed your baby, no way of making your stay a little bit more enjoyable, no car, no money, no job, no house. 
​And you wonder, what the hell am I doing this for???!!!!! 
​I'm so fed up with my life
