Need some good counsel

Hello friends my name is Nikolai. I'm from Orange County California. I'm 39yrs old and I've been spending hours a day researching a new career. I was a X-ray tech/medical assistant, also a cable technician for many years and now ive been doing debt collections for 3 years. Out of all the jobs I've looked at getting my full stack keeps popping up and is something I'm passionate in doing. I've recently been excited to stop looking and start doing. I'm very much a beginner with not much knowledge at all so I need some help. I have questions. I've looked into universities, community colleges, bootcamps, I'm getting tons of calls I'm ignoring for now.

I want to know the best way to move forward.

● What's a good way to start on my own and what should I start with. Any ideas? Free online sites that are nice a easy, good books?

● out of the full stack should I start with front end first then back. I want to gain some knowledge of the basics before getting into some type of school.

● what is the best route for getting certified and building portfolios, as in school. Uni, colleges, bootcamps. And what would be the best of out those to join?

● what is the best languages to learn that people want for hiring you?

I'm not even sure the questions to ask, I'm sure I'm leaving some out and will have more going forward. But I'm sure you can see I don't know what I'm doing and just want some guidance on the best path forward. I'll take whatever advice I can get and filter it to the right direction for myself. I'm interested in making friends with those in school, out of school and looking for jobs, those who've just been hired and especially those with years of experience. I'm interested in making some friends. Thank you for taking the time to read this. And I'm excited to learn more and
