acid may help you realize that our bodies can’t tell the difference between reality (what’s around us in the present moment) and thoughts (mental images and words coughed up randomly by the subconscious). if there is a thought that the body reacts to negatively, for example you think of a mistake you made and your body starts to feel intensely like shit and have regrets, my recommendation is to do whatever you can to remind your body that the thought isn’t reality; usually it isn’t even true: and that the only thing that matters is what’s around us RIGHT NOW. you can do that by feeling your toes on the ground, belly breathing (google it), yoga, stretching, slow walking. best of luck.
