<human>: Summarize the given text in a few sentences.

So there is this girl who I have been friends with for about two years now, I would like to say that we are pretty close. Her sister and my friend have been joking around with me about how I must like her, and it started to get me to think. After a lot of thought I decided they were right, unfortunately she has left for college (which is a 4 hour plane ride away) and I am unsure what I should do. I really value the friendship I have with her and I would never want to lose it, but part of me also really likes her and I am not sure if I should tell her or not. I haven't ever really talked to her about dating or anything so I have no idea how she would take it. What should I do? I also forgot to mention that I am 16 and she is 18, and I am still in HS.
<bot>: Starting to realize I have feelings for one of my very good friends who just left for college today and is a 4 hour plane ride away.
