S'NL: Welcome. Rebel gave some mighty practical advice. Take that list and customize it for your own use. You will need to think ahead so that your actions in the present tense will lead you to your future tense goals. Local and regional governments offer the best chance for you to latch on to some higher education/training and you can look up what's available online or check with local agencies or librarians to assist with research.
Many of us had to walk a path that took years to complete, but you will be just fine. We're all here to help you and to challenge you! We want you to be successful at this fading business but it's not for the faint of heart, I assure you! One thing that really helped me was to move away. I tried to move locally, but I was not successful at that time. Then I bided my time, organized myself, and moved some distance away. It was quite liberating.
Your reading older threads and thinking about them will be a consolation for you as you start replacing the false and insincere friends with new acquaintances, new ways of looking at things, and a different outlook. A remarkable journey is just ahead. You got this.
