Lost to life a life of pain

My whole life I have been rejected by everyone around me. My friends have left me at every corner, my family no longer talks to me, I feel lost, disappointed and constant emotional pain. In 2010 I tried to focus on university and work, while ignoring and attempting to make the most of my situation. However things became harder. I lost my motivation, I was left by the few friends I had and at 19 I had never kissed a boy, as I was afraid of being judged at left by the one thing I had, my family. This year I finally decided to deal with my sexuality. I have been brought up in a christian home, however at 20 I thought it was time to try and live my life without the fears of what others thought. However I have learnt that life is not that simple. My entire life I have tried giving to people while putting on a happy face. I am always there for everyone and when someone hurts me, as they often do. I tend to forget and let them hurt me all over again. Every close friend I have had in my life has left. I’ve now come to the stage where no one talks to me, unless, A: they want help with their work, B: they need money, or C: they are bored and want me to be their entertainment for the day. I have to initiate virtually every event, and now afterwards I feel empty. I am seen nothing more than an object to everyone, even my family. My emotions are never considered, I am only ever seen at face value. I have a decent amount of money as I have worked extremely hard, and for my age I am highly educated. However whats the point? Everyone in this life is cruel, I constantly am treated like shit and I am now at the stage where I am incapable of making new friends. What’s wrong with me? I really don’t understand. Some things that happen to me, make no sense whatsoever. It’s like how can you really be that insensitive? I started balding at 18. Does anyone know how hard that is to deal with? Everyone mocks me, once when I was invited to someone’s small party which happened to be on my birthday, people started singing happy bald day. It’s like I’m cursed to a life where I will always be alone. I need to escape this pain. It has been here so long and it will never leave. I want to kill myself, but I’m afraid of hell; although it’s like I’m already there.
