so I'll give you a (kinda) short version of what's been going on.
My whole family has been overweight for generations. My mom is overweight and has been all of my life and now she has been diagnosed with diabetes and still continues to eat entire bowls full of sugar free pudding and all other kinds of 'sugar free' crap.
anyway, 7 months ago when I started Atkins she was SO SUPPORTIVE of me, she constantly told me I looked great and called all the time asking if she could watch my 3 year old so I could walk. But slowly she started acting really weird toward me, she doesn't want to go shopping together, she not only refuses to watch my 3 year old when I need to exercise but she purposely makes plans to go places on the days that I've had to work so I've had to call in a LOT.
She's become more than obsessive about every little thing that I'm doing, if I call and tell her I'm doing something she always INSISTS it's the wrong way.
Example: my 12 year old dd has to get braces and has to have 2 teeth extracted. I tell her that I'm taking her to the dentist and she INSISTS that it is not the right thing to do and CALLS AND MAKES AN APPOINTMENT WITH MY DAUGHTERS ORTHODONTIST!!! This has set our braces appointment back by at least 4 months.
NOTHING that I do is right anymore and everytime she talks to me it's in a pissy, rude way.
I'm just completely baffled by what to do. I wonder if my weight loss has anything to do with it, but maybe I'm just being vain? I HAVE started to do what I want and live for myself and our family has been doing so much more together because I am active now.
She has basically turned herself into a hermit, she never goes out, refuses to go to public events like Christmas parties or 4th of July at the park, and she thinks that we should just all stay at our homes and never travel or explore the world around us.
It has gotten to the point that we have been looking for houses further away from her because her attitude is so rotten and mean. I am just not sure what to do, we used to be good friends and now she just snarls everytime I am around and is all happy and jolly to everyone else around her.
any advice? Thanks for reading, this is all so weird.

What a HORRIBLE situation! Sorry to hear you're having to go through all that. Have you straight out talked to her and asked her why she's behaving the way she is? Let her know you love her, but that you can't tolerate being treated like that by anyone because you deserve better. Hard situation and I wish the best for you!
thats just the way we were raised, ya know? 
She is not a 'going to the doctor' person, as I mentioned, she's a homebody and only goes to the doctor if she thinks it's a life and death thing...there's not a chance that she'd ever consider anti-depressants. She is 53, I am 30
