Have you looked into AVRT or RR? I found making a big plan helped me so much.
It also gave me the skills to talk my AV down...There were days when I felt that as long as I could tell my AV to shut up I could get control over my out of control AV.
Remembering HALT..Hungry Angry Lonely Tired. it helps. Also sometimes just calling the day quits and going to bed.
I find the milestones are the toughest as well.
