I guess I missed it, but what are you going away for and for how long?
As far as being blacklisted from a career? Fuck it. Dave are you really that enamored with accounting that you can't picture your life without it? I have worked nonstop for the last 6 years just to make it to a credentialed actuary and now that I'm here I think I want to switch careers because it's not for me. It happens. I could very easily live the rest of my life as an actuary, make a very comfy living, retire before 55, and that be that. I've made a lot of connections in the field and there are things I like about it, and hell I might go back to it, but it's just a line of work man. If you're a clever (notice how I didn't say smart, I don't give two shits how book smart someone is if they can't be clever in their solutions) hardworking guy you're an asset wherever you go. I think too often people marry themselves to one career. Fuck that. Explore shit. If accounting is out for whatever reason then what's your next interest? I promise you it doesn't have to relate to your degree if that's what you're worried about.
Don't worry about the student loans right now. You've got enough on your plate don't add another thing to the stress fire that you can't control until you find what you want to be doing anyway.
Go to the gym because you like to work out.
Finish the classes now because you're so God damned close there's no reason not to and then worry later if they mattered or not
Don't date until you have Dave figured out. Trust me trying to have a girlfriend play counselor and fill the void of you not loving yourself with her loving you doesn't work. I've tried that. It just hurts both people.
If you need an escape, escape. I've felt that way. Bought a plane ticket to Austin. Visited a friend from school. Things got too hard for me. I needed to get away. I got away for a weekend. If you need longer than that adjust as needed. But fuck it man. Life's way too short to feel trapped. Go do something fun. And if you're tight on cash mega bus. Or just fucking drive. And chill. Relax.
