Regrettably, it's a cocktail of highly interrelated psychiatric issues:

1. cPTSD 2. ADHD 3. Depression 4. (Relatively mild / high-functioning) autism spectrum disorder

Likely combined with aftereffects from mild traumatic brain injury (i.e. a high number of concussions), but this part is largely speculative.

Would not recommend attempting to research your way into a solution without the help of a trained practitioner.
