Yes Yes Yes I totally agree!
In order to eliminate emotional parasites, it is necessary to discipline the mind, which means taking time out of your regular daily activities to deliberately think positive thoughts, and train the mind to remain focused on them. Every time you catch yourself thinking a negative thought, immediately move your attention to positive things.
Remind yourself and your body that you are loved, you are joy, you are truth, you are whole, you are a Child of God/Nature/a higher vibration, and as such you are rightfully healthy. You are well, your body is a temple for higher conscious dwelling. You are love, you are powerful, you are prosperity, you are confident, you are integrity, you are wisdom, you are capable, etc. etc. Speak these things out loud to yourself.
When the critters send out chemicals that make you feel anxious, depressed, afraid, deliberately stretch your face into a big smile and hold the expression on your face. Feel what it does to your face and neck. Know that you are in charge of your body and it is up to you to create an environment that they cannot tolerate, so they will have to leave.
They thrive in the midst of negative emotions. Go to funny movies. Leave the serious political activist work to those who are physically stronger for now. Once you have complete control over all your thoughts, you can participate again, consciously, without becoming food for worms. If you have a sense of futility about the condition of the world and the state of political affairs, you will only add negative emotions to the situation.
Your task is to spend time out in nature, taking care of yourself until you have grounded yourself the ultimately reality eternal peace. Only from that place, can you be of valuable service.
Please forgive me, and remind of this, whenever I forget. I am learning to do it better, as I write this. Thank you for reading this forum.
