Mid-Semester Burnout

It's that time, and it's not even mid-semester. This is like one month into the spring term and I can go on no longer.
You see, as much as I love working at Cafe Nasty, with its superior brew and its quirky employees, there will come a time in the next couple years where I'm certain I'll go crazy and have to leave forever. I'm not approaching this state, but I've witnessed other former co-workers get there and it's not a pretty sight. They get cranky over the littlest things, their eyes are dead, their vveins drained of all the love they ever had for working here. Hopefully, I'll be able to pull out gracefully before it gets that bad.
I've got like two more years of college left and I plan to stay at Nasty until I've graduated and hopefully gotten a jobby job.
I'm bringing up these concerns over burning out one day just because that's sorta how I feel at this moment. It's the whole working and schooling full-time that gets me. And living with my darling boyfriend and making time to spend with him. Forget about having other friends. I'll have a night with the girls every now and again, but still. I feel dried up right now. Emotionally and psychologically.
I know that I'll be better tomorrow. Good Night.
