Last week I met this incredibly sweet and cute girl. She is 3 years older than me. It turns out she is dating one of my best friends. I acted normally until one day I randomly got sick. She thought it might be because I am jealous of them. I'm not the type to get jealous and that was my first time that I thought I might have a crush on her. Now I get depressed and sick when I'm not around her. I just want to stay friends with them both, but I don't know if I can get over my emotions. Can someone please help. I've never felt this way before but I just want to be friends...
