Hi sorry for the short reply. 

I agree that with my BP1 my depression hits hard after a manic episode and the longer the more regret and then depression kicks in. I've had BP1 for most of my life I'm now 51 but I wasn't diagnosed until I was 47. I find that things I can't control or change are to be left alone and time and soul suckers and I finally learnt how to look after me and better myself. Through my experiences in life with mental illness is that every one needs to try as much different types of treatments to see what works for them unfortunately that takes time. 

Take care
