My investment in RDN feels like water boarding

Since I bought it on 11/12/2008 at 3.51, I am underwater most of the time, but from time to time, there are chances to gasp for air, RDN is trading at 3.3, looks like I will have another air time in the next couple of days. The problem is what should I do if I am profitable again, hold on, be prepared to take another round of water; say good bye to water boarding, take a small profit and run. I think I will continue to hold until the day I sense it is no more water boarding, it is actually drowning. I guess, it is very hard to tell drowning from water boarding in the process, no matter how many times you have been through it.

Just recording some of my feeling in the difficult time of investment. Thank you for reading.
