What to do?

What to do when you are afraid that you'l loose your friends after the University? What to say when you are truly afraid of that life? Yeah we are always afraid of the new and yeah sometimes /mostly it is good, but still. Every student has this wow that after the Uni I will move out from my parents's house. If you are single and afraid of most of the stuff can you do it? How will it be? How much you and your life will change until you reach the end?
Yes, this is a call for help. Call for the future to show a way. I really just got into the thinking that I will loose my friends. Because everyone wants to stay where they were born but I want to explore, because all the man that maybe are waiting for me are away from my home. I can feel it. I need to go. Or I just want to explore and try out. Live a little as the say. Maybe during summer I will try.
