college just isnt for me???

im a single mom. ive tried on 3 sepreate occasions of going to college to improve my quality of living for myself and my daughter. i have a decent job but its kinda dead end. im not bored with the job yet but year after year i get just a little fed up. i dont know what else i can do to make more money except work two jobs and im not doing that. the only other option i have is getting a higer education. Ive tried school several times with intentions of becoming a nurse( always dreamed of being a nurse)but i hate college and i didnt last long. my grades were mixed some good, some bad( my math skills suck)so what else can i do?

Sincerely, hopeless single mom

- EDIT

* Thank you ladies, i might give school one more try. but slow and steady this time 😉
