The only advice I can give you, guys, from my personal experience is to always be yourself and to always trust that the people who love you right now will love you when you come out. If someone changes his/her mind, it is just because he or she didn't really love you.
And also do not feel pressed to come out. Each of us has found the appropriate moment to come out. You will know when it is the best time to do it.
Be yourself and be as happy as you can!
