Oh man, I had MAJOR issues with this when I was your age. I would try to get in on the jokes (which were mostly pretty mean to everyone involved) but I would just end up getting sad and taking things personally. It was so hard to laugh at things when I was too busy worrying about what people thought of me to notice what they were even saying! I struggled through the years, mostly because I just cannot seem to get down with the teasing jokes, they just seem cruel to me. Finally I accepted that it wasn't for me and the problem went away! Once I accepted that I couldn't handle the "mean" jokes, if a friend made one about me, I would make a sad face or say "your so mean!", try to go along with the joking while also not reciprocating the teasing. My friends totally got that and stopped teasing me. Now (I'm 26 now, so people are WAY more understanding and kind then when I was 16) my friends don't make jokes like that. Those jokes aren't even that funny. Me and my sister and my boyfriend CONSTANTLY make jokes and crack each other up, but we are total dorks and our jokes are awful puns and clever humor, and if it ever goes too far, we are quick to apologize because we love and care for each other. It's hard to find people like this when you're a teen, but know that the kids around you will probably grow into nice, respectful people someday. (hopefully for them!)
