Pep’s for energy during the day and to improve sleep at night?

I am a 33F SAHM, 110 lbs, current stack tirzepatide 3mg a week, 1mg GHKCU daily, 500 mcg kpv daily. I’m chronically tired and sleep is awful. No energy for workouts and no motivation for anything except my kids, but even playing with my kids feels like a massive task and it shouldn’t. Eating 3 meals a day, cals around 1200-1500 a day. Drinking 8 glasses of water minimum. Any suggestions?
