Sorry if this is a bit of a weird one!
I find that just before I fall asleep, in that limbo state between wake and sleep, some thoughts that I must suppress throughout the day/when in full consciousness involuntarily flit through my mind and drive me MAD!
Such as:
"God, I'm so unhappy with my weight. I've really let myself down!"
"DP is losing his hair and I'm actually quite sad about it."
Does anyone else get this? Sometimes I lie awake for ages with these thoughts going round in my head!
