Hey Ad- I was going to recommend the same thing Acc did but we both know he can state it better
I really think prioritization is key here. I get the same overwhelming feelings from time to time for trying to do everything and its just not possible always.
I know you are ultra talented, competent, confident, etc.. but we are basically single parents now so try not to beat yourself up or feel ashamed for not accomplishing everything you wish to.
Even people in a coopertating dual-parent household would have trouble accomplishing everything you are trying to.
