I would definitely heed Mark's advice. I had a similar injury that was exacerbated by alcohol. About 14 months later, I still have headaches but many other symptoms have gotten much much better. At 18, please know that your life is most definitely not over. I am 25 and the last 14 months have been excruciating but life is long and you're just going to have to grow up a little bit sooner than your peers. But, you got this!!

Mark, with all due respect, I really do think you need to take a look at the tone you use in the backhanded questions, making people who are reaching out in a very troubling time feel dumb or stupid about their injuries. I know you've lived longer with PCS than most of us on this forum, but what I'm suggesting has little to do with PCS and much more to do with just showing a bit more empathy. No one wants to be on this forum, regardless of how young or stupid you might think they are.
