I need someone, or something.

You can't let one girl ruin it for the next girls to come. That mishap that occurred should be taken as a lesson. It's okay to trust people but you have to also watch your surroundings. People are sneaky. You've stopped trusting people because of fear of betrayal. In your mind, you probably see it as that if one person can do it to me, I wonder who else can do it too? I'm here if you need someone to just listen to and let all your emotions out on. I don't know you so my opinion won't be biased. You seem like a very sweet guy who just needs someone to open up to. I promise you'll feel better once you take all that weight off of your shoulders. Try not to over think too because over-thinking will create problems that were never there to begin with. Listen to music. Music is a great escape to go when you need space away from the world.

Have you tried journaling? You can put there what you don't feel opportune to share with people. As for girls, make some girl friends, read or watch works made by women, you can date when you are ready but in the meantime you'll get to experience that not all are like the one that hurt you.
