Am i crazy? love sick? or gettin played?

i go to school in the south and she goes to school up in new york. she tells me she stays busy and its believable because she goes to an ivy league school. she never really texts me, once every two weeks MAYBE if i'm lucky. never answers my calls or returns them (and no i'm not stalking her). i miss her and think about her alot. i don't bother texting her because i either wont get a reply or she's too busy to talk long. i'm a bit depressed, i really miss her and i just am not functioning like i usually do. the hel do ya'll think is goin on?
