@Simmon, having had the benefit of "talking" with you on yesterday's Chat, I believe that one of your biggest roadblocks is your regret and guilt that you agreed to have the surgery, even though there were specialists who said not to. You are now blaming yourself for making the wrong decision, and you are well on your way to convincing yourself that you made a terrible mistake which you must now live with for the rest of your life.
This is a false story, made up by your fearful brain.
You are very young, and your body has already healed. You have seen a lot of doctors, and as far as I can tell, you have no restrictions on what you can do physically. The big thing holding you back is that you must forgive yourself.
Self forgiveness is the first thing you must accomplish. Without that, the next step cannot be accomplished. There are a lot of resources out there to help you learn what it takes to forgive yourself - choose ones that are based on therapeutic practices, for example

The next step is to figure out why you had such extreme pain at such a young age to begin with. This is not normal! When I see such a young person with such severe issues I automatically wonder about the family and the environment growing up. You will have to look at that if you want to fully recover.
To do the emotional work, there are several options. One is the workbook that Scotty recommended. Another is the Structured Educational Program I mentioned in one of your other posts. Individual therapy or counseling, as you mentioned yesterday, is always worth exploring.
