I don't care so much about specific times/days.
But a consistent T is totally vital imo. there's no way I could come to a place of healthy attachment if my T wasn't reliable enough in her reactions towards me. There still is plenty emotional chaos - coming from my side

A consistent T can feel scary to me a lot of the times. Inconsistency and emotional chaos feel much more familiar to me. But deep down I know that emotional consistency and reliability is the road towards wellbeing for me.
