I think you just read my mind. That is SO much like my life! Right now the big one is obsessing about changing careers (from engineering to veterinary medicine, so yeah, completely starting over). I spend hours upon hours (at work, mind you) researching and planning my new career. Then I get pissed at my husband when he won't let me turn our world upside down at the drop of a hat.
I have absolutely no good advice for you, as I struggle with this essentially on a daily basis, but I am writing to let you know YOU ARE NOT ALONE! Feel free to message me, I would love to get in touch with a kindred spirit. And lots of hugs.
