Wow. You're clearly struggling now and I feel for you. Wish I could take you out for a girls only weekend and just shoot the breeze.
Sometimes the unknowns are the hardest to sit tight through....all we can do is sit and wait.
As for taking the kiddos to a hotel pool, hey! nothing wrong with that. At that age, they will have life-long memories of it. I do still recall going to the community pool with my cousins very fondly.
You're a good mom and a real good person. Don't let anyone tell you otherwise.
