There is absolutely NOTHING wrong with being Bi and nothing wrong with being DIFFERENT in general! If I wasn't different from my friends, life would probably be boring! Unfortunately, people who are different tend to get teased or made fun of about it. However, there are likely many of your friends who will still be willing to accept you as you are. Bisexual/Homesexual, etc. are normal variations of human behavior. They are not "illnesses" and they are not bad.
