How to find root cause of my depression and change this?

I've suffered of depression and anxiety for a very long time and various reason from time to time. In the end I've overcome it by myself because I did't find therapist who really got me and yes, sometimes I felt like I would have never come out of it. To me so, find the root has been essential in order to overcome the problem. Ask yourself questions, try to think about how it started and why, try to think how would you rather be (the answer is not simply "better", but try to imagine scenarios of how you want your life to look like and which person you want to be). Remember you are important here in this world, so think about what you want to do. It doesn't have to be necessarily something giant, think how could you improve your life and believe in it. Some people say we attract the things we focus on, what I know for personal experience is the way you act, you think and what you focus on slowly becomes your reality. So create your world, be the person you dream about being. The way you talk to yourself Is critical. Try to be less judgmental and less pessimist, rather focus on good memories and good dreams. You have the answer inside of you, you know yourself better than anyone else. For me helped immensely find a purpose in my life, find something to wake up in the morning for, and be more mindful, enjoying all the beautiful things that happen around me each moment. I know it can be hard, it can be extremely hard but try to focus on that. You create your own life, so your future doesn't have to be controlled by depression, it will be only if you want. You are here in the world to be a wonderful being and live a good life and it can start today.
