The same with a weakness in Kedusha or Ka'as or Kin'ah, Sin'as Chinam, learning Torah, davening without Kavana, or coming on time for Minyan, etc. You appreciate your low Madrega, and your pain is much less. It says in Mishlei: וְאִ ם תָ רוּץ ל ֹא תִ כָשֵׁ ל ד יב Watch out for running too fast in Avodas Hashem. It can cause serious problems.
“But I’m doing terrible Aveiros!” It doesn’t matter; as long as you try and desire to improve. The Gr”a says that the main reason for the giving of the Torah was that we should acquire Middas HaBitachon. Being Sameach B'chelko is #1, and therefore the lack of Simcha causes Churbanos, Rachmana Litzlan, as it says in the Tochacha: תַ חַ ת אֲ שֶׁ ר ל ֹא עָ בַ דְ תָ אֶ ת ה' אֱ לֹקֶ יךָ בְ שִ מְ חָ ה וּבְ טוּב לֵ בָ ב תבא כח מז all the punishments come for lack of Simcha. Whoever gets S’kila (stoning) first gets thrown down from a building. And if he isn’t dead, then they stone him. (Mishna)
The only place where being thrown is mentioned in the Torah: יָרֹה יִיָרֶ ה יט יג (“he will be hurled down”) is here by the sin of touching Har Sinai. Perhaps it’s a Remez, that if you’re too high, you will be thrown down, Chas V'shalom.
