Maybe you're just feeling really run down. Sure skip a class as long as you think you can handle making up for it. Relax a bit. If you don't have time, make time. Also, in 5 years are you going to say 'I'm proud I dropped out of school with 2 years left and have ______ job to show for it.' or would you rather say 'I'm proud that I worked through the tough stuff and earned my degree and now I have _____ job to show for it.'

Life get's hard sometimes and you just want to rest. There's a quote "Scared is what you're feeling, but brave is what you're doing." Maybe we could change that a little to say: 'Exhausted is what you're feeling, but persevering is what you're doing.' Just stick with you. You'll be good.
