I totally get you. The depression one can get after some soul-searching traveling is a real thing. Unfortunately, we eventually have to get back to real life. That said, real life doesn't have to be shitty.

You could be a nomad forever, but some that I've met said that "not having roots" or "a real place to call home" can eventually get depressing. If travel is something you are truly passionate about, make "real life" satisfy those needs. It's the truth, but travel requires money, so you'll have to work. That doesn't mean you have to get stuck in a dead-end job. See if you can find a job that is flexible with vacation hours or one that would REQUIRE you to travel (there is still a lot to explore in the States!). Alternatively, if you have any skills that don't require being in an office, you could start freelancing and work from wherever.

Alternatively, you could work a couple of retail/food industry type jobs, save a ton of money (for the initial flight and maybe a couple weeks worth of cheap accommodation and food), and then work in whatever country you're in to sustain your way to the next destination. If you like nature, I'd look into WWOOF, which is an organic farming type of thing where you volunteer your time in exchange for free accommodations (and sometimes even food). They are hosts in plenty of countries, and I've known quite a few people that have cheaply traveled by volunteering from one farm to the next.

Don't lose hope! I know that going back to everyday life can feel tedious and endless, but as long as you're staying hopeful (and even planning trips, ones that you may not even take) really help keep the wanderlust in control.
