Like most other people commenting here, I don't have advice on the career path—in my case, it's because you haven't given any information about what your strengths or interests are besides programming. Could you give us a little more info on what you enjoy, or what you think you're good at? What did you like in high school or college? Do you like math? Journalism? Lab work? Politics?

Aside from that, I have one other piece of advice that you may or may not enjoy hearing:

I would stop—like, right now—even thinking things like "I experience PTSD-like symptoms". (Unless you're dead serious about your symptoms being similar to that of those who really have PTSD, in which case get a real diagnosis from a professional.) There are many reasons for this, two of them being:

1. It's hard enough for professionals to get this stuff right without getting their diagnoses called into question (including by armchair-psychiatrists like us programmers on HN). Heck, people here are even questioning your assessment of the CS question's difficulty. (!) And there's so much context and prior knowledge/experience to evaluating symptoms that's difficult to judge as a layman. Just go on WebMD next time there's a weird pain or tingling or bump somewhere in your body. If your experience is anything like mine, you'll quickly find that you may have anything from M.S. to cancer... when in fact it might be nothing more than a cold (if even that) and it could go away after a while. All you're doing is depressing yourself.

2. The point of identifying any illness is very simple but very critical to keep in mind: to help find you a treatment for current or future symptoms based on the known literature. If you're not doing that, then telling yourself you have—or might have—a disease/disorder isn't doing you any good. Again, you're just depressing yourself. And what's worse is that you're suggesting to yourself that you don't have control over what's happening, when in fact there's quite a good chance you do.
