Typically, when I edge down this path, I de-clutter my life. Stuff weighs you down more than anything else, and it's a constant drain on your energy and money. Stop doing things that are unnecessary, get rid of some stuff you don't / won't use, and generally purge your life of everything that really doesn't matter. It'll free up a lot of free time, and likely money-pressure too.

Once you've got that, take your new-found free time, and do some experimenting / soul-searching. Odds are you "know" what you want, you just don't "know" it. And if you don't, maybe you'll discover it. Take each day as it comes, and don't re-clutter until you've figured things out.

I've also found that music typically helps me a lot, so I make sure to get some frequently. And no, everyone is not handling it "just fine". Everyone struggles at some point, you may just be hitting it earlier / later than those around you. Or they're just hiding it, which is likely more harmful than seeking help, so congratulations. You're already part-way down the correct road.

edit: mimicing what edkennedy says, I've also found that decent exercise and good food are very important. Food's extremely responsible for well-being, but it's easy to devalue.
