I would think you might wish to deal with the bullying first.
Why is that taking place. And for what reasons. Once that
is put to bed so to speak. Running track. Distance runner
would be appropriate for someone with a swimming background.
Good Flexibility and lung stamina over the years of swimming.
You could actually do both. I do not believe they would run
into each other during the course of the year.
Mountain biking. Sounds like you would have the legs and energy for it as well if you've been swimming for 4 years, all year round.
Do martial arts. MMA, shotokan, aikido, taikwando, judo, kung fu, amok, ju jistu, etc. it will toughen you up and you will enjoy it. I reached my black belt in shotokan in 8 years. Teaches you discipline, self-control, self-defence, etc.
my sister is 12 and she plays football (soccer), it is not just for boys. I'm a girl and I love it as well. You won't get bullied for it as more girls play it than you think. Kick a ball around for a bit with your friends and see if you enjoy it!
Good luck :)
