No, you probably cannot sue:1) The statute of limitations (or time limit to sue) for a personal injury in TX is only two years. Even if you could argue that as a then-minor, you could not bring a legal action until your majority, that was still four years ago; hence it is almost certainly too late to bring a lawsuit.2) Even if it were not too late to sue, you could only recover money if you could show that the school or the program was negligent, or unreasonably careless, in some way--such as by having you do an unreasonably dangerous event. If they were not negligent, they would not be liable for your injury. Not all injuries result in compensation.
