I'm feeling really down at the moment, if you were me how would you handle this?

You are an amazing person or you wouldn't be able to have these deep feelings for another human. You have to believe that there is something to learn from this. I know you are insecure so you should get excited about the possibilities of what is out there and learn how to be more secure and see other people. You can't live your life leaning on someone else. In a relationship it is best to have someone to help hold you up during tough times but not everyday. So learn your lesson and get to searching. Get a new hairstyle, buy some new makeup, get your nails done...do something to give yourself a boost and quit crying. You are beautiful and an amazing person and it's your time to shine.
