Remember these few things

You don't need to become a mechanic, you need to learn how to fix this one problem on the one car you have. Car parts stores will even loan you tools for free.

You don't need to become a plumber, you need to learn how to fix the one problem with the one toilet in front of you.

People probably won't give you much if any money, but they will happily share knowledge for free. It doesn't feel like it right now but the knowledge is more useful in the long run.

Every new challenge like this that you beat makes you a bigger badass for the next set of challenges, which is good because life will never stop giving you challenges.

Most people want you to succeed because we all love an underdog story, by helping you they get to play a small part. Exploit this when looking for help, you are in a bad spot now but this is the exact path you will take out and how the thing you are asking for will make it happen.

I've lived in my car in hard times before. When people know that history and that you beat that situation the respect is immediate from everyone forever.
