There's despair at HEP, yes, but it's because we can't discover a Higgs boson every year and many physicists thought that maybe there were lots of new particles coming up. There was a solid theoretical possibility that would have allowed in a way to get something similar. But they're not there, or at least we don't have the means to produce them now, so you have to try other things. That's not bad, that's simply how science works.
You can't make up new particles if they don't exist. That's not a failure, that's the sign that you have done your job. The better you get at something, the harder it gets to improve your results. No one tells biologists that they have to get something better than Evolution every decade.
That disappointment of many can't spoil what has been a triumph, the Standard Model with warts and all is how Nature works: there really are Higgs bosons which we didn't have the technology to even look for until now. And there are still precision measurements to be made that will give us information about what we can't reach directly, because it's hiding in some numbers there. Such things don't make it to headlines, though.
About fundamental physics... Well, we've discovered that neutrinos have mass, that's new physics right there. We've measured gravitational waves, which many thought was impossible. We've discovered that the Universe expansion is accelerating, more new physics. Also that dark matter is pretty much not an hypothesis, because of weak lensing and a number of other independent observations, so there's exotic matter out there. There's a lot of work to be done, yes, but we've learned a lot already.
