My cousin used to start huge art projects with wild excitement then leave everything half finished while she slept for days, and we never knew what to make of it. Im trying to understand if mood swings like that fit bipolar disorder. Can you recommend a reliable place to read about signs and treatment options in the US?

I get why you are curious. A friend of mine used to paint nonstop for two days straight, barely eat, talking a mile a minute about new ideas… then shed sleep for what felt like forever and ignore everyone. At the time we just thought she was intense, but later she got a bipolar diagnosis and said those swings were a huge clue. If you want something clear about signs and treatment in the US, I found bipolar disorder treatment near me really helpful for understanding what I missed.
