provide an income for me and the kids

The last time I earned an income was when I got pregnant with my daughter, then I got sick, then had the car accident, and now here I am 4 years later struggling to make it all come together. I have a vague idea of what I need to do and I have been working towards it but no one in my life supports what I’m trying to do. Both my mother and my ex have been treating this as some kind of hobby and pressuring me to give up the whole idea and either get an office job (which I’m still not physically able to do on a full time basis) or just live off of them. They don’t seem to understand that I want to be able to buy things for myself without asking permission- I want to know that if everyone else dropped dead I could still care for my children. I want to set an example to my kids. I want to be able to do something that I can be proud of, that can make money, and that I can be good at- something that I can be appreciated for and not taken for granted.
