energy tank running on empty

I work full time and I feel like I use all my energy taking care of others at work (nurse). By the time I get home I am zapped and don’t have any of the love, patience and understanding left for my amazing family. I want to be my husbands “girlfriend” and have energy to goof off with my kids. Instead, I find myself to mentally and physically exhausted to put forth the effort – literally just trying to make it through the evening rituals, to only sit mindlessly facebooking or something equally wasteful. If I don’t lose my shit before dinner, its a win. I don’t want that to be what I/they remember about this season in our life. Ultimately, at the end of the day, I want to feel I have something left to give to the ones I love most. I don’t think its safe to consume anymore caffeine then I already do. I workout, have a decent diet (beside possible caffeine OD) & generally pretty healthy. Any tricks I can use to get my “evening” brain in the right place to push past the wall I seem to hit most days?
