I can be ridiculously excited about things, usually followed by some embarassment because I should stop being so excited and just act like a normal grownup. But to hell with that: if I'm happy, I want to show it :D
I had to learn to not let people take so much of me that they left me empty. But I cared so much that I couldn't see it. I had to learn the hard way when I finally realized a close friend was using me for her own gain and giving nothing back. Give, care, but dont let others take you for granted or use you. Sometimes we have to put ourselves first for our own physical and mental health.
