In my experience, advice to "suck it up" usually indicates a lack of understanding on the part of the advisor, and an assumption that your mental state is similar to that of the person asking for help. The OP is asking for strategies, alternate ways of viewing things, ideas he hasn't though of or dismissed. "Suck it up", is something we all try, or attempt to convince ourselves we "just" have to do. It usually doesn't work. The brain is changed by tricks and nudges, not some doomed-to-fail attempt at overriding yourself through (easily depleted) willpower. If sucking it up worked for you, then you are probably in a very different situation.
