So I’m pattur from eating in the sukkah if I start thinking about the tzaar I’m going to have later if I have to shlep blankets to the sukka when I go to sleep?! Are you really saying that?
If you’re (really) having a panic attack every time you see a Sukkah, I could see a hetter to not eat in a sukkah.
Let me ask you. If someone has true PTSD from a Sukkah. Let’s say someone saw his entire family killed in the Holocaust in a Sukkah, and he himself came within an inch of death, so that whenever he sits in a Sukkah he breaks down in tears, would he be Chayav in Sukkah? From the Klal “Tashvu KeEin Taduru”, I would say no.
