What actions have you taken so far? Are you working through any books or online courses with actual homework problems?
For all the things you mentioned, a good start might be studying calculus. Even if you studied it in high school, you're probably rusty.
If I were in your shoes, I would sign up for mathacademy.com ($50/month) and commit 2 hours per day (14 hours per week) to studying math. This would both help you develop a study habit, and ensure you have a good mathematical foundation for the other things you want to do.
In my experience, trying to study things that require some math foundation (like all the things you've listed) can be really hard and demotivating if you're missing those prerequisites. It can feel like you're not smart enough.
