HELP! I'm on an emotional rollercoaster?

ok mr.emotional roller coaster chill out take a deep breath. what your going though is normal. it dose not mean your a girl it means you have feelings and having felling really sucks sometimes.the reason you liked that girl so much is simple she was nice to you. you were having a crappy time and she reached out to you.so no you are probably not in love just grateful. from what i gather u r graduating high school that's a huge step and your sad because your leaving things behind and your going to be sad its change and change is upsetting but now your start ting a new adventure. this is going to be scary and new for a while but before you know it high school will be just a distant memory.
