If you can't handle the heat, step out of the kitchen. There are more safe stocks out there to invest in if your stomach is not capable, simple as that. There is no need to keep trying to persuade this gentleman from selling when/if he breaks even. Let him do what he wants and if it goes up, it is a life lesson learned. If it goes down, it was a smart decision, simple as that. Either way, don't keep moaning on about your churning stomach.
If you want to do something, simply do it and get it over with.
