Am I crazy?

Ok either I need a reality check or I am right and it's just the system. I've been a single working mom for a over year now due to my ex husband going to jail. Been without him for just as long. So because of these circumstances I've literally taken over our entire finances we had together. At the time we were together he was working full time making roughly 18ish an hour. I was bringing in about $400 at the time. I now make $13 an hour and have covered a lot of what I could and sold off made it work where I could. I'm now finally getting our house we had sold and will be getting a decent amount off that. My thing is I don't want to keep working at a daycare I want to spend time with my 3 and 1 year old like I was when i was a stay at home mom. I don't want to miss out just because my ex messed up and tore up our family. I know this is a very hot button delema and I already know some people who are going to say why can't you just keep working. The answer is I can but I want more I want better for me and my kids. I love being around my kids and truthfully taking care of children comes naturally to me. I wouldn't mind being a nanny or watching kids in my own home, but idk how to get to that point. I'm scared if I buy another house I don't think I can make enough right now doing that to make a mortgage plus other expenses. I guess I'm looking for anyone who's maybe figured this out and knows how to make a good income while still being with their kids.
