Go to yearly survey taken by stackoverflow and you will see list of mostly needed languages.
Pick one path and dig deep into it.
Aim for the knowledge, clean code, understanding how everything works under the hood.
After that you can easily switch to any language in future.
Programming languages are nothing but a tools that would help you build stuff. You would just choose the one that suits you best for project.
/e If you have never been into CS field, nor you have chance to learn it with your current education plan - my advice is to start with online lectures from Harward CS50 lessons. (Google edx CS50)
It will be a hard work to finish all exams and earn a certificate, but after it you would be able to find a work as a junior developer as soon as you finish it.
It starts and ends with:
Scratch (to get you familiar with programming logic)
C (you would learn all basics, algorithms, linked lists etc etc)
HTML
CSS
JavaScript
Python
Final project
About 10 weeks of lectures, and one year to finish all assignments to earn certificate.
