You describe several circumstances that will affect your academic performance negatively.

I have been on 6 different schools. I failed 4 times. I gave up for almost a decade. Then I succeeded. I can't really explain why. Now, I might be an extraordinary case, both positively and negatively,

What if you have no negative distractions and what if your academic programme is manageable?

That said, some people indeed aren't college material. And being convinced of that yourself also doesn't help. So I do not know what is the best in your case. But for sure important things are making sure your life is set up so you can succeed academically, and having the mindset where you believe you succeed,
