Matzah, etc.

Hello Rabbi Michi!
I finished the psychometric test yesterday!
How are you on such a pleasant Passover Eve?
(The truth is that I just remembered the attack on the Park Hotel in Netanya on Seder night, and it disgusted me.)
I have colitis, and matzah gives me severe stomach pain.
Yesterday I went to the emergency room because of intestinal inflammation.
How can I fulfill the mitzvah of eating matzah?
