I can almost relate to everything you wrote! Although, my job isn’t *terrible* and I feel lucky to have it, I am unhappy. I feel like there is more I should be doing, but I have no idea which way to go or in what direction to take. Good luck on your journey. I have no advice to share, as I am in the same position as you, but I felt the need to respond. You are certainly not alone in the way you feel.
Peace
