You can not improve your situation immediately. You have to work permanently on this moment. Control your negative thoughts, go for a walk, set your priorities in life, start doing something really important.
To be happy, you have to eliminate a few things out of your life. It’s not easy, but it’s needed.
See what you need. So you will understand that there are things that prevent you from being happy. Refusing is to end a cycle of life.
No one is guilty of being unhappy. It is our fear who destroy us.
