Every punishment and sickness in the world comes directly from doing a specific sin. Here are some of the punishments we get in this world & what the מדה כנגד מדה is. We think if we laughed at a wedding in front of 40 people someone is going to laugh at us in front of 40 people. NO NO NO that not the מדה כנגד מדה of laughing at someone, tell me which sickness is similar to laughing at someone? Think! Coughing! You get a cough until you realize what you did, do you know what stuttering comes from? Talking too much, don’t you see that as it is you are having a hard time talking just be quiet etc… A lisp comes from talking לשון הרע. As it gets shorter & shorter. Hashem is begging the person to stop & saying don’t make me turn you into a mute stop now, don’t you get the hint from seeing your tongue getting shorter & shorter?.
May we all wake up and do Teshuva very soon so Hashem our beloved father doesn’t need to keep sending us punishments of all kinds of sicknesses
