My Hypo mania is great the sun is shining puppy kittens and I love the world. With in 2-5 days I go Mania and it’s a ugly full of rage , anger and self loathing , feel worthless.
Mixed for me is both Mania and soul sucking depression at once , to me it’s pure hell on earth.
How to prevent ??? , practice self care have a huge tool box of coping skills and know how to use them. Take medications as prescribed. Practice sleep hygiene, eat healthy , exercise , get outside daily, add yoga and Mindfulness to help find your balance.
Just know that sometimes no matter how hard you try .... Bipolar will in fact reach up and slap you at some point in the future
Are you in Therapy ? If not I suggest it it can be very helpful staying stable.
