Is it just me?

Lately I've been SUPER clingy with my husband, I'm almost in tears when he has to leave for work. I end up feeling depressed and unmotivated to get anything done till he gets home, but he works 50-60 hours each week and is working on med school applications so even when he's home we don't necessarily get to see each other. 🙁 I feel bad because he does everything he can for me and will even stay up late to listen to my rambling (even though he has to be at work at 3am). Is anyone else feeling like this???
