If the answer to the question is "yes" then I have an idea for you. All it takes is a piece of paper, a pencil or pen, and yourself(of course)
Write most or all of your problems in life. Then, crumble it up as tight as possible and throw it in the trash.
I promise you that you will feel much better. Being sad all your life is bad. It lowers your self-esteem, and you don't want that.
Find the good things in life and hang around positive people.
