The advice I want to give is to tell you to concentrate on one or two of those tasks that are most important to you. Focus your energies there and do what you can with the others, but don't stress over them. maybe? And most CERTAINLY, don't be afraid to ask for help! You shouldn't have to carry the weight of the world on just your shoulders. I know as women we tend to think that's our job, but it's ok to ask for help.
Hugs to you.
