if it's early in the war, you might be just below their depthcharges which they may set to 150 meters. Sit tight, cut the engines and keep the planes on dive (thus keeping yourself grounded) while repairing all repairable damage and getting all the flooded water out of the boat and only then try to come up by blowing all you have.
I survived a similar ordeal once (although I wasn't quite as badly damaged)
much flooding after significant DC damage, grounded around 180 meters with the 12 or so DD's from warspite taskforce above me. They sailed off after a couple hours by which time most damage was repaired and the water from the flooding was gradually being pumped out. Only then did I blow all the remaining air and we made it back home.
Good luck with the engine/fuel situation though
