Is it normal i want a new startstart

I am 35, single parent to 3 kids (youngest is 3) and am starting to look for a job to support us all. I used to work as a hairdresser, and also worked from home when kids were small, but I want a new job and this will not earn enough money. Also I can't work full time as child are costs are too high. I was in an abusive relationship for a long time with kids father and he knocked my confidence down, and I feel I want a new me? Is this normal to not want to do the things you've always done? People assume I will go back to my old job as its a kind of safety net, but I don't want to. I'm not sure what I want to do yet, just something I can fit around the kids so I can spend as much time with them as possible and not have to put them in child care when they are not at school. Thanks....
