Hi,
Stress will bring symptoms back and slow down recovery. I think in time whether months for some, years for others, you are less vulnerable to set backs and you recover quicker if there is a set back. My son who is 7 months out has been virtually without symptoms. School is going well, he can study long hours, run on a cross country team etc. Over the past weekend he did too much, stayed up late with friends, did a walk for a fundraiser, studied and was tired at the start of the week. He stiil seemed to be O.K until we added the stress of his drivers ed. test midweek and then I noticed"the look". This is the look of fogginess and he gets complaints of being very tired and nausous. The stress of driving in an urban enviroment fliped him over the edge. He took a day off from school, slept alot and then woke up, passed his driving test and has continued for a week now to be without "the look". He is bright eyed and has alot of energy. I keep trying to slow him down in fear of it all coming back. I notice that with rest he bounces back and functions great again. You really have to pace your recovery. I think you do recover and it all fades away with time. Stay positive and do not let depression or other emotions confound your recovery. I think my son is doing well with not thinking about it and enjoying life as much as he can.
