Working to an unreasonable deadline is sure trauma.

In my business they schedule our R&D like breakthroughs can be planned. You just have to accept that you will be behind schedule and over budget and be immune to the unavoidable beatings.

I once put forward a plan, naively an optimistic one and leadership and planning cut my plan and budget. We pretty much performed to my original plan but I was subjected to weekly earned value beatings.

Don't beat yourself up even if you take a mental health break. Progress is at best slow and steady. Setbacks can't be rule out.
