hello!!! welcome back! Sounds like you've been super busy and stressed out! You are a good person for welcoming your mother into your home, Im sure she really appreciates it! It must be hard on you though too. My mom once moved in with me for 5 days while she fought with her hubby, she is only 53 though and fully capable, within 5 days we were already getting on each others nerves! However my house had NEVER been sooooo clean! And it was nice to come home to a nice meal for those 5 days. She does not work so she cooked for me, cleaned the house and food shopped! hehe And she took the boys for walks and brushed them everyday!! However I can't imagine it going on for more than 5 days! haha
Anyways, good luck with everything, sounds like you and your mom are just taking some adjustment time!
