What is really worring is that gap between you lines west and north of your bulge. You must reinforce it.
First try to orginze Pz Div withdrawal as a whole. This would neatly serve to cunter the threat in that gap. Split them Inf units and put them in the same hexes with Pz Divs units in contact with the enemy then try withdrawing them (it's a kind of game, they might fail to disengage).
Secondly use some of the leftovers from dividing to immediately cover that gap west of the bulge.
Thirdly put some unit(s) on that hex with the unit still in transport. It will be the last defence line and point of exit. Also very good chokehold to stop pursuing Soviet units.
I wish you luck and hope you'll be able to get out most of your troops
PS. Your defence in the bulge are quite strong. By taking 1/3 of them you increas a risk of them collapsimg but not by large. I cannot see the strenght of Soviets which are in immediate contact with your units but I wage they mostly will hold.
PS2. The withdrawal should be achieved in 1-2 turns. It has to be quick so you could reestablish your line of defence.
Plans are worthless, but planning is essential.
