Glad to hear from you Jarp, we miss you and are here to support you.
You sound overwhelmed, and rightfully so with all that is going on. Take care of yourself first - remember what the airline stewards say "Put on your own oxygen mask first and them help others"... If you don't have oxygen, you can't breathe and take care of anyone else.
Starting a new high powered job is stressful in and of itself, and I would imagine will start to sort out with more weeks on the job.
In the meantime, try to sort out child care so that you are not so reliant on your husband. Will your mother be back soon to help?
One step at a time, keep your head above water, and in time, those steps will add up and you will be at a longer term solution.
Keep posting, we're here to support you
