Do go on the trip. You need to keep following your own interests and activities. I used to do the same kind of thing-checking the temperature of the R before making any moves myself. Problem is, if things were going well I'd want to stay and enjoy it, if things were going bad I would want to stay and fix it, if things were uncertain then I'd want to stay and get to the bottom of the uncertainty. I was so focused on the R that I forgot how to live for myself....and that only exacerbated the R problems.
