It's alot !!! I think we don't appreciate how many things we are juggling !!! I'm sure you have every right to feel burnt out !!!
I hope you can plan a night out or a weekend to pamper yourself and to recharge !! I am a planner and try to have meals in the crock pot so at the end of the day if I want to veg I can . I do get 2 hrs in the afternoon that I just sit !! Have a tea and recharge !! I also have 'planned' a tv time after naps so that everyone is ready to have snack together , so my afternoons seem alot more peaceful !!! By the time diapers are changed and snack I only have about 1/2 to go !! ( mine all leave around 4-430)
Maybe cut back on crafts for abit !!
I hope you feel better soon !!!!!!
