I was diagnosed bipolar-2 about 20 years ago. I have had difficulties with medications, most caused worse problems than the disease. This was partly due to being treated for depression prior to my bipolar diagnosis; we figured out I have bipolar when one of my depression meds caused a serious manic episode. I found meds for anxiety worked for me, as it just concentrates on anxiety, the part I have the most difficulty dealing with. I used klonopin for this, but I could not drive while on klonopin, so it was not practical. Seroquel was helpful, but hard to manage. I would take it when I was manic/anxious, and it allowed me to sleep. It makes me super sleepy, so I used it exclusively in the evening. I found I could only take it for a few days running, as it gradually drove my mood down. So it had some value, but it was not ideal. I currently take CBD, which works better than any medication I've every tried. I buy CBD gel capsules (33mg CBD each) and take 1 morning, 1 evening. I find it works best to take it every day, even if I am not feeling anxious.
Stay strong
