Improve psychophysical well-being

dear Jody, thanks for writing to me. I am sorry that you are experiencing these inconveniences, in order to be able to give you an answer, we need to talk about them better so that we can get to know each other better and therefore find a solution to your problems. Waiting for your reply, I greet you warmly. David

my day is fully loaded, and because of this, I feel squeezed out like a lemon. There are a lot of thoughts in my head that prevent me from living and thinking normally, I get distracted by them, and therefore I constantly feel tired. After how many classes will I feel better?
