Walaykum salaam. Just remind yourself that you are exactly where you're supposed to be. Being home for your kids is a big blessing and working moms (me included) often wish for what you have. As Maram said, it's never too late!! Online classes or evening college. And even starting work from home (being a nanny, food business if you're a good cook etc.), will be good to start earning something while you're in school. May Allah make it easy for you
Wsalaam, it’s never too late to go college or learn new things, when you put your mind to it it will happen inshallah, online courses are readily available as the comments say above! Inshallah everything will work out for you x
I know it feels impossible sometimes but it really is never too late! Have you tried look into online schooling? There are also courses that take only a few months to get certified as a phlebotomist or medical assistant if you are seeking to go down the medical route! As for the kids try looking into activities within the town or city you live that are free, the local library is usually a great place! I hope this helps!
