I just need a break

Took my kids to a playdate today at a indoor play area. Fed them two meals and a snack. Been running around continously. Now 3 and 1 they won't take a nap. Each pooped. They can't stop talking to keep eachother up. I'm just burned out. I'm in a flare with my autoimmune condition and am in tears. Husband is working late tonight. I just needed a break. I needed them to nap to nap he crabby. I am burned out today. The cold is so hard on my body and no chance to sit down has really broke me to tears.
