I'm heavily broken and I don't know what to do

I thought as you gre older things got easier...or rather you learned how to deal with problems. I don't know if it ever gets any easier. I find myself being content...almost happy, and then something happens and it stops and I feel lower than before. I don't have any way to shape the way I feel to make people understand. I don't enjoy being depressed and lonely. I don't. I know some people think I do...but I don't. I just don't know how else to be. It's like, I am so used to feeling this way that it is my norm. I hate not trusting anyone. I hate feeling so lonely. I feel like I have no one to turn to, because no one cares. I just want to be happy. I just want to be whole. I want to belong. I want to be wanted. I want to be needed. I want to be loved. I want to be fixed. I don't want to be broken any longer.
