I’m sorry, OP. I had a similar experience with both of my kids, and they are now 5 and 7 and sooooo much easier. Some kids are just harder than others -very clingy, sensitive, etc, while others just go with the flow better and can play independently. I remember having a kid for one weekend alone at that age was so hard. We got through it by taking turns with DH to each have alone time to recharge, and always stuck to a strict bedtime routine so that we could veg once kids went to bed. Trust me, it’s not you. Hang in there, celebrate the small happy moments, and know that it will get easier!
