no don't have gf, it's the age to study. if you feel empty have friendship with the girl you like
If you really like her then get a gf. I know how it feels when you don't have anyone to talk to. She can be someone that doesn't distract you but rather motivate you. You just need to be with right person who is there for you when you need them but you need to manage your time and focus on both the areas.
