Anyone else get sad when they have to go after spending time with your bf?

After hanging out with my bf I feel so sad before leaving to go home. I always feel like it will be forever until I see him - even if it's just a couple days. I wish I could see him everyday and wake up/go to bed with him - so even if we're busy I'll still be with him. Anyway, I could just be extra sappy because pms but I have a big week of clinicals coming up so I won't have a lot of time to see him this week 😪
