The Left out one

Ever since I could remember..I've always been the odd one out, the 3rd/5th wheel, left out of thing when hanging out with my friends. At first it's okay, but after a while it tends to hurt ones feelings of this constantly happening. High school it was the worst for me. Every day most of my "true friends" left me out of the loop of things. Once I graduated, I promised myself it would never happen again. Well importunately it happened to me again today. It's been a while that I forgot how bad it hurts. I was suppose to have a movie day with one of my friends that I have not seen in a month because she was too busy hanging out with her "friend" that was interested in her brother. I was there at her house when..what do you know her other "friend" came over. Then from there I felt like...the odd one out and it hurt me. I believe this happens to me because I'm heavy set kind of girl. I guess one can only learn from their experience and grow stronger from it.
