Well thoughts are your viewpoint and they create emotions. If you view the world as a scary,unsafe place, then you will have feelings of fear. If you view the world as a safe, positive place then, you will have feelings of peace and safety. This is true for all life situation. When I start thinking about things in a really negative way, then I start feeling scared and angry, which for me, then affects my body. If I can remember to stop myself in my tracks and change my thought process to a more positive dialogue, then my feelings become more positive and my body feels strong and non-stressed. And it's okay to feel angry about your job and it's okay for those thoughts to pass and you don't need to resist them. But you don't need tone fearful of them or hang onto them either. You can accept them and then let them float by. They are just thoughts and you can choose to let them be but not let them define you. If you can just allow these thoughts to pass through, without hanging onto them, you will be learing the art of detachment. Detachment means you have no expectations of things being a certain way, or you feeling a certain way and therefore these situations and thoughts no longer have control over you, but it takes practice. See, when I get scared or angry, my back started to hurt and my head starts to ache. All of my body pains are coming from my thoughts which create emotions which, then comes out physically. Hope some of that makes some sense. It's daily practice for me. All of your reality comes from your thoughts. That's why everyone's reality is different. Everyone is creating your own reality through their own thoughts. You can change your reality by changing your thought process. But remember to first always face the emotions head-on and journal about it so that you can let self heard, and then are able to let it go easier.
