Janet, I do understand, I truly do! Things just get overwhelming when they pile up! I know you've had such a stressful time helping your mom. It sounds though, like things may improve there. I hope she is feeling better, physically, with the dialysis - she should feel better soon, if not already!
I would worry about Ricky driving too - but the payoff is that he will have a great education with many many employment opportunities. So, in the end, all of the worry will be worth it - but you already know that, and it doesn't lessen the worry.
I would worry too, about renting a house. But all you can do is get it clean and sparkling so it will be ready to show to prospective renters. Make it as inviting as possible. Can you plant some pretty fall flowers in the front? Anything to make it welcoming. Surely, you will be able to rent it quickly.
I am the worry wart in my family. I know it drives my husband crazy and so I just try to keep it to myself. Worrying doesn't do a darned thing to change things, so why do I do it? Just like your husband, I worry too much, and I don't even know why. But I do try to keep it to myself as much as possible - or I rant to you all. LOL!!
