My question is if your wife has had the oportunity to learn about bipolar from non-bipolar people. Maybe you should look into NAMI which is support for people living with people who have mental illness. Support people need support, too.
I know some people are resentful of the idea of "when things get hard, you get to take a pill, what do I get?" But really, wouldn't everyone rather not be on or require any type of pills and just live life without all the problems of illness? Of course!
Another thing, if you really start into remission with your meds, then I think she will see the difference. Sometimes seeing is believing, you know?
If you're looking for therapy and can't find anything check out the DBSA and see if your local chapter has any suggestions. Good luck!
