Your mind is making a lot of rationalizations and justifications in order to protect yourself from further pain. So you will look to the bad things and then you don't feel so hurt. That is OK, it is normal.
Your coach's suggestions are something that you will probably review at your next session. Looking at what you DID and any possible effects that might be due to those changes and then adjustments will probably be considered.
While you indicate that you already knew the things your coach suggested, are you doing them? How are they working for you, so far?
