No, this world would not be better off without you! You don't have that many people in your world because you are afraid to open up to people. You think there is something wrong with you and you afraid if they knew how bad you are, they will abandon you. First, understand that there is nothing wrong with you. Do you see how many people are lonely? Do you have a co-worker or a neighbor that can invite for cup of tea? Listen to them - they are same as you! Have compassion for others and yourself! Be the first who reaches out for people. Know somebody with a child like your age? Invite them to the park, or to do something! You will be amazed how many people will want your company! Don't wait for others to get to you, get to them first! And always remember - your idea about yourself was formulated by others in your life, but it doesn't mean that they are right! Most of the time those people suffering from the same problems as you, just take it out on you, and in result you think there is something wrong with you when there is none! You are wonderful and there is so much you can give to the world!
