If the same comment ruins your day every time, that’s not about them anymore. It’s a spot worth looking at.

A remark that lands hard every single time has help from the inside. Most throwaway lines pass straight through; the ones that reliably take out your day are landing on something already sore, which is why the same sentence keeps working. That is not your fault and it is not an accusation. It is simply where the bruise is.

Name the comment, then name what it touches: being thought stupid, being left behind, being the one who does not fit. Say the plain version to yourself once. Then decide separately what to do about the person, because the bruise and the behaviour are two different problems.
