Hi Buty, nice name.
I'm no expert on these things, but here are some of my rambling thoughts on such a matter.
Everyone has as much right as everyone else to exist. Nobody has more right to be alive than anyone else. We are all blessed with the gift of life and are entitled to live our lives.
Some people will be better than you at doing certain things. That does not mean they have more right to exist than you. Some people may be considered to be better looking than you. That does not give them more right to exist than you. This is YOUR gift of life. It is not for anyone else to decide how worthy you are. It is for you to decide how you wish to live your life. This is YOUR gift of life, to do with as you please, to explore things that take your fancy. Never forget that.
Other people may appear to disapprove of certain things about you. So what of it? It is none of their business. It is not for you to tell them how they should be, so likewise, it is not for them to tell you how you should be. Why should you be ashamed of yourself? Because others in society have made you feel that you have something to be ashamed of? But what is it to do with them, this is your life, not their's. You are only ashamed if you are worried about what others think of what you do, but it is none of their business what you do. They have no more right to exist than you.
If we were all birds, would you be worried about the other birds thought of you? Or would you just fly and enjoy the freedom and your gift of life?
ok, that's enough verbal defication...someone else take over, please...
