Stop putting all of your hope into one thing or person! Do NOT become fixated on them because you are building yourself up to be let down every single time.
This could be a complete overreaction but it's a good lesson. You do this to yourself every time, you get your hopes up and they are always crushed because the world is not made for overly trusting and hopeful people like you. It is made for the cold and the emotionless who know what they want and aren't afraid to take it.
Get yourself together you are a fucking mess.
You will get through this and when you do, focus on yourself. No one else will take care of you, no one wants to deal with it. Being cynical is a good thing, don't let anyone tell you different. it is realistic and you need to be realistic right about now. Fuck emotions and drop them right away because you don't need them. You need to get back to your many goals and you need to be in a better mental place before you start focusing on boys that want nothing to do with you.
