It is so challenging, but you have to fight the urge to give up. I've been there so many times, times that honestly I curled up in a ball and cried thinking that there was no way that I could continue to fight the disease. But in each instance I realize that the disease is winning, and I refuse to allow that to happen. Yes its tough, and certainly a roller coaster ride of emotions, not just for me but my family and friends as well. Don't give up Parus, keep the faith and continue to find ways to overcome the urge to quit, and if that means professional help please do so. It took me far too long to realize that just having someone to vent with, as well as be provided insight and suggestions on how to cope was long overdue. My pain psychologist is the absolute best at what he does, and is the one who has helped me maintain my sanity through my personal journey.
