I'm Worried That My Wife May Have Bipolar Disorder. She

I'm worried that my wife may have bipolar disorder. She takes meds for depression, has been taking pain meds for 10 years for her arthritis. She stays in bed 24\7. She is always depressed and now seems addicted to on line video games. She has spent over $2200 in the last few weeks on games! How do I get help?
