Please don't feel sad & embarrassed.
Almost everyone has been where you are.
I've been in situations where I cried & was supported - I've also been where you, unfortunately, which is not supported.
Tonight, try to go to bed soon with a relaxing book, podcast or watch something easy, if you can.
Tomorrow, do a check on the situation - are your senior managers responding with support and actions?
If not, take some time to itemise the challenges leading to stress. Tell them what you need. Clearly say that you & team is working hard, but it's unsustainable.
Meantime start evaluating your options about staying or leaving.
If you stay, look for where you can take agency around your workload. Step back, let work slide if needed.
If you are going, start preparing a strategy.
Things will get better 💐
