The plants around you are not supposed to heal you. They did not grow thinking “I would like to help boost someones immune system today”. They follow their own agenda in this world. Their compounds have not evolved to ease your pain. They have evolved to allow the species to survive and thrive.
They can help you but never heal. You have to heal yourself.
In the same way, the people around you are not meant to help you. They have evolved to have their own agenda based on the chemistry in their bodies. If your parents would not feel good when they see your face then they would stop liking you.
Understand that no matter how many things you use to help you, the last steps you must take yourself. Your mind, your emotions and your body will have to do the work.
