I think your T may be talking about 'compartmentalizing' your problem. Usually compartmentalizing isn't considered a positive thing... instead of coping with problems, people put them in compartments & lock the doors & eventually the clutter builds up to the point where the compartment just explodes.

Sometimes you have to put certain problems in storage so you can get on with your life. Then, when you have a quiet moment with nothing else pressing to take care of, you can go to your mental storeroom, take a box down and deal with whatever you stuck in there. Sometimes it's the best thing to do with things that happen that really, really piss you off. Instead of responding immediately, over-reacting and saying or doing something horrible, you can stick the issue in a box & see if it wilts once it's not exposed to direct sunlight.
