Why is it so hard for me to create any type of relation with people?

Ask yourself what it is that you want and need from people. Be ruthlessly honest with yourself. Remember that most people are busy trying to get what they want and need as well. Being able to identify both your own desires and other peoples desires will allow you to make better decisions about whom you invest your time in. If you have to do most of the "balancing" right from the start or are the one who "starts all the conversations", then stop right there and wait until you meet someone who will be more of a partner in your life right from the beginning. I'm sorry to say that it often takes a long time. Good Luck.
