I'm not sure man, I'm in a similar situation as I intend to start up lucid dreaming again after my exams are over. I would just say persist and if/when you get some lucid dreams hopefully those would be enough motivation to continue ;_;.

I'm sure some of the more serious lucid dreamers will offer better words of wisdom than me though as I expect that they've probably faced similar situations and overcame them.

Good luck with getting back into lucid dreaming!
