I'm so confused for you.. there was so much positivity in your sitch recently.. and then it just took a turn. It's likely just part of the roller coaster but I totally understand if you're too tired from the ride so far that you feel like getting off and having your feet on solid ground. I think taking a much needed breather and doing absolutely nothing regarding your M or R before making any final decision (as per Dry Heat) is a smart idea.
I agree with BBJ.. your D's are so blessed to have you for a Mom.
