I knew a guy that was in your situation. He did research at another medical school before matriculating to my alma mater. Every job, even as a physician (with clinicals, paperwork, patient population, etc.) will have a boring/tedious side to it. OR tech is an amazing gig, especially if you didn't have to do a formal training program at a CC for 2 years. If I were in your shoes (and parts of me wish I could go back to do this,) I'd take up a new hobby. Weightlifting and physique competitions are what I was into, but I could never do it because medical school and (now) residency are top priority. I'll be about 36 - 40 years old before I could even devote adequate time to compete. And, sadly, physique is a young man's game.
You have a lot of time to yourself, even with the MCAT. Really appreciate not bringing home work with you and having that time to enjoy the company of others; find drinking buddies, friends that share your (new) passion, and explore the dating scene in your town/city if you're single. Even if you think it's dumb (like raising horses,) do it.
Hike the Appalachian Trail from Georgia to Virginia.
Do a 31-day challenge to do something new everyday. For instance, my buddy started with something small like "eat at a new restaurant OR go to a favorite restaurant and eat something you've never think to try." At the end of the challenge, he had to find a girl he'd never met in his life to go out with him (on a date) THAT NIGHT. It was some sort of way to make him more outgoing, and it worked.
Move into your own place and learn to be an adult. It will do wonders for you in the long run. The non-trads/independent traditional students in my class whom worked and made a living on their own fared much better than those who've just graduated college and had mommy and daddy pay for everything. Learn how to budget, make payments, and still have money to throw around. F*ck it, blow an entire paycheck on something stupid, like upgrading your car, getting an Xbox 1/PS4, go out of town, spend it on a date/girlfriend/boyfriend.
You're at the prime of your life friend; take advantage of it. Medicine is NOT the end-all be-all of your life. It boils down to a career that you devote your life to for the next 60 or so years.
