I believe he means, the magic isn't working.

Tigger. A feeling isn't a gift from outside of us brought in. It is inside of us going out. That was a perpetual window, not a quickly closing door. You remember happiness now. Nothing else will be good enough. It is time to seek change. Find joy again. It is within you. You know what won't work. What will? (rhetorical)

Have your mourning period. It is healthy. But notice that you said 'nothing else would' instead of 'nothing else could'. That is telling.

I wish I could help more.
