If you are interested in the field, it might be helpful to pay for a teacher and ask for advices. A teacher will be able to trace a path from the level you are now and help you learn just enough math for you to get started. It's way easier, take less time and is less frustrating. In France it's possible to get a math teacher from 30€ to 50€ an hour.
