Yes, I feel happy between episodes, even not being fully functional. Do I feel euphoric happiness when stable? Very very rarely. Living life for that is not a reasonable expectation. Perfectly mentally healthy people feel blah a lot, too, and often "just go through the motions". However, I'm guessing your "blah" is a little more than that right now. Maybe it's hypothymia. I've had that. Being just a touch under or over the hard target of "stereotypical normal stable" is common.

I have found that therapy and certain actions and sensory stimulations can help shift the mood a bit. When hypothymic, I know I have to push myself into pleasure a bit. I do dislike the saying "Fake it until you make it", but think pushing oneself to do normally pleasant things CAN something clear the clouds a bit. Discovery, learning, mindfulness of the beauty of nature or other things can push me into another realm to a degree. I try to pick healthful things for these pursuits.

Some little things that give me pleasure are:

* Writing

* Going to a local pizzeria where the staff are always happy I came and one person even gives me hugs.

* Finding new recipes

* Teasing my parrot

* Showing love to hubby

* Walking across the bridge a looking at the river

* Flower arranging

Simple pleasures added up are crucial in life. Big ones are great, but should not be waited for exclusively.
