I expect this has something to do with the relief, the heightened mood and lack of oppressive feelings you get when in the session. In real life I find that this intensity is not commonly come by, otherwise life would be rather strange.

I think you have to work on the issues in therapy between sessions trying to understand how the insights in therapy help you day-to-day. Likely this won't be entirely straightforward, but the areas you find hard to manage you can take along to the next session.
