Too shallow to get a girlfriend?

I'd say you should wait a little longer. I'm 18 and I've started my second year of college a few months ago, and I changed a lot over the past year. I think a lot of people experience something like this, so maybe things will get better for you after going through some changes. Around this age you'll still be defining who you really are. Chances are you don't even know what you're really looking for in someone else right now.

Either way, try meeting as many different people as possible. The more people you meet the higher the chance that you meet someone you like and who might like you back.
