Mindfulness really helps. It is a necessary skill whether you are on medication or not. Journaling can help you start to learn mindfulness. I highly suggest going to therapy too. Medication can help, but therapy and medication together is best.

Were you diagnosed with bipolar 1 or 2? Because that really changes things

I was diagnosed with bipolar 1

I don't even know. I was in severe depression for 9 months and only had small moments where I felt okay after getting on latuda (I don't suggest this med because of the 350 cal requirement and I had the side effect of severe drowsiness, I now having an eating habit of eating right before bed) Now what helps is working on building habits (the book atomic habits helped get me on track)
