@210030sa the mistakes are in your past. You learn from them and move on with your life. If you have any arrests, I would think that since you were young and a minor that they should not show up in any background checks done by future employers.
Start thinking about where you would like to go to continue your education, visit that school in person (if you can due to covid) to see if you like it, and then apply if you do. You can take general courses at first to see what direction you'd like to go with your classes.
I also strongly suggest that you see your doctor. It sounds to me like you have some anxiety and your doctor could prescribe some medication for you. It would help so much with many of your struggles and make continuing your education much easier
