Firstly, although you may be lonely you are certainly not alone. Understanding comes in time, and having been picked on for being a very large guy I can assure you that what happens now will be something that can form you into a man and a true gentleman.
I agree with the other guys- try out a nice low buzz- say a 1 or 2. You may find that you really like it. Don't hesitate to talk- to friends, family forum or God and always remember that nothing that is transient in this life has the ability to define you. You are not your hair, whether it is long, short or non-existent.
