I know exactly where you are coming from. After some years of hearing this, I finally just decided to say “thank you” to the advice instead of rebutting or self-critiquing and kept on moving with my life. I know what my experience is and no one else can tell it to me or live it for me. Remember that every day, in every moment, you are doing the best that /you/ can. You are the only living in your body and you are the only one who will in your body. You are the only one responsible for your body and no one else can tell you what to do with it or how to manage it.
