I pretty much gave up everything as well.
I stopped hanging out with friends as much. The schedule for classes, rides, and clinicals got too crazy for my job, so they fired me. I used to go out to karaoke as a stress reliever every week, but I stopped going. I'm not a very good student in general, and I wanted to do well.
After ridding myself of all the distractions, I'm now top of my class. And since my course is coming to a close in a week or two, I'm studying like crazy for my State and National licenses.
Once I've got those in hand, I can pick up where I left off in my social life.
My cutting everything out was a choice for me. Because I don't just want to "get by" in this profession. I want to be damn good. So I work hard for it. Almost like an obsession. But like I say, I'm not the best student. It's a little harder for me to retain things than others, so I really have to work at it.
It may not be the same for you. And if not, more power to you.
But since I'm top of my class and doing so well with everything, I'm warranting myself a break this week. A little karaoke celebration. So I got that going for me. Lol.
My point is, if it gets too crazy, don't be afraid to give somethings up. The people that truly matter will still be there cheering you on when you come back 'round.
