I know what you mean about dating people in the same profession... that was one issue I had with this guy i dated from my program.
and I'm alot like you too with being a nurturer and I totally eat all of that up.. when you're alone its not as fun . We're also pretty much the same age.. I'm 24 August 13th.. so pretty close to you.
Plus.. its really true that EVERYONE around me is getting married. Four girls in my program just got engaged (all 22-23 years old) and my first roomate in college just got engaged.. as well as my roomate last year. Its ridiculous. It just makes me feel more single than ever. haha.
thanks for commiserating.. are you almost done with school.. or how have you branched out to make new friends?
