Interview burnout

How do you guys deal with interview burnout? Esp when you have back to back interviews My brain is wired to not do anything else before an interview because i try to not get injured or fall ill and stuff like that And after the interview i tend to overthink every answer and what i could have done better Is this relatable and if yes what do you guys do? Every interview and every email feels extremely high stake and I truly want to give up this feeling because everything is a phase and will pass
