Nick,

Yes, my username is absolutely a GOT reference (can't wait for the new season).
I know exactly what you mean about the social isolation this condition can cause. I am 24 and like you, have friends that spend most of their non-working hours at the bar. Since I haven't been able to tolerate that environment, I spend most of my time at home as well. I feel like at our age, it is hard to find social activities that don't revolve around alcohol or over-stimulating environments!
Also, not exercising is a tough thing for me, since I was so active before my accident. I am currently doing 30 minutes on a stationary bike almost every day but all I want to do is to go running or hiking again. Like you said though you can't sit around feeling sorry for yourself so I've adapted and picked up some low-key hobbies to keep me occupied (apparently I can draw pretty well, who knew!).
I'm glad you have a girlfriend who supports you, that is so imperative in this type of situation. My boyfriend for over a year gave up on me after the 7 month mark , so you are definitely lucky!
I think maybe taking time off work for the summer may be good, full-time work could be hindering your recovery. I'm in the opposite situation, I've been taking it easy for almost a year (very little work and no school), but think I need to start doing more and getting back to a normal routine, because who knows when this will end and life must go on! But like you said, we will see.
Anyways, sorry for venting, but I am discovering that this forum is a great community for us survivors and since nobody I know personally can relate, I figured I would just throw my thoughts out into cyberspace haha.
