Many, many people feel that way. So you are not alone. Abuse can make us feel isolated, and make the world seem cold. It can make us afraid to open up to people, and accept love. The good news is, you are not alone, you are not worthless. You are a human being that deserves happiness, love, and tranquility. Sometimes it is hard to find strength when you feel like you are looking at the world from the bottom of a hole in the ground, but you can have all the happiness in life that you want. It takes time, work, and more often than not, inner turmoil. I wish you the best and want you to know that you are not alone!
