Crush

When you have a crush on someone it can throw you off, It feels that if I think too much more about this my head is going to explode. But when I am with them, they make me enjoy being here like I made the right decision. I have had more fun hanging out with them than I have for a very long time, but all these negative thoughts keep flowing through my head and I just want them to stop. Can I not be happy? I'm scared, what if they're just messing around and playing with my feelings, or what if they are doing the same thing to other people at their other job? I just want to be happy but I don't think it's going to happen, I most likely won't get with them because my mind is in the lead right now and I don't have any energy to try and fight back.
