Need advice

OK so lately my OCD has made my mental health worse, it has made me depressed and stressed so right now me and my boyfriend live on our own and we have 3 kids we also have some debt from a few credit cards we've used and this has made him have to work more to pay them and we have a car payment so he works a lot I mean a lot and is hard on me mentally and physically because I take care of the kids always and I'm always alone and ocd it's bad. So we wanted to buy a house but we need his credit score To go up again so we were thinking of maybe renting a house with his parents so we could split rent and pay off our debt and at the same time he wouldn't have to work so much so I could also focus on bettering my mental health but we feel a bit embarrassed like when people find out we moved back with his parents of what people would say like we couldn't make it on our own or something and I felt embarrassed but my health is also important .

What do you guys think would it be a good idea to move with his parents?
