You don't like it, change it. Go on a diet, work out, etc. However, you need strong will power, this will be probably one of the hardest things you will ever do in your life, and trust me, you will feel much better about yourself.
Be patient, thankfully your doing it when you are young, by the time college hits (When most people find that special somebody or go on dating sprees), you will not only feel better about yourself and your condition, you also will be much more confident and healthier.
