Sleep problems seem common. I sleep well most of the time unless I have a major worry causing anxiety. I never get cross with myself for not sleeping.
I tend to wind down in bed and when I turn out the light, I find a comfy position, turn over then back again (not sure why) then imagine myself in a safe environment and create a story in my head of how my ideal life would be there. I seem to just zone out shortly after.
I really don't like labels. There is a condition cyclothymia which seems to be a milder form of bipolar. I prefer to think we are all the way we are because of our genetic's and our upbringing. Neither of these do we have control over.
Most of us do a wonderful job of managing ourselves. It is hard when our needs don't match what our partner needs.
I send best wishes to you and your husband.
