Even though you may not think you have control over your emotions or thoughts, you are the one who controls them because they are your thoughts and emotions. Or you can allow them to take over your body.
Change your perception of the thoughts and what you are feeling. Find meaning behind what you are thinking or feeling. Replace what you are thinking or feeling with a positive reason or outcome from what is happening.
In the end, they are your thoughts and emotions and you need to control them
This has a lot to do with attitude. If you think you can, you will be in control of your thoughts, emotions and actions.
