The supervisor is responding to the BS he's being told. OP isn't telling the supervisor "I have emotional problems that lead me to procrastinate as an avoidance mechanism". He's telling him something like "oh yeah I'm totally making progress with task X you gave me, I just didn't finish it because I went into task Y and made progress there instead".
