T.S.
First off, CONGRATS! Buying a house is a big deal and I'm sure it's stressful. Maybe your mom's just under some added stress too. My mom has a knack for this herself. It sounds as if the circumstances surrounding your mom's house being up for sale to begin with may not have been her most favorable, so being under that stress for what ever reason and also knowing that her "little girl" ('cause you know we're always their little girls) is a single mom and about to take on the wonders of home ownership, maybe she's a bit scared for you too and instead of verbalizing that she's afraid for you for whatever reason she's instead being negative about the idea. My mom does the same thing. I have to tell myself that she doesn't intend to be negative, she's trying in her own way to guide me... all be it a bad way to guide, it is her way. LOL Maybe slow down and have a talk with Mom, let her know how you're feeling and why. If you can, show her how you plan to care for the house and that she has nothing to worry about. I know my mom worries about whether or not I'm organized enough or make enough money, or have enough time, etc. I'm betting this could be the case with your mom too. Have a talk, get it out, and hopefully then together the two of you can enjoy this experience instead of dread it. I think it's wonderful that not only are you doing your best to provide for your son, giving him the stability of the home he's known, but you're also helping your mom. That's wonderful!
