Girly, I thought I would add some sympathy and support. I agree with whoever said that you may be too close with your mother. I feel this myself at times, although we live about 30 miles from each other, we phone very often, I am an only child and am very close with my Mum, something that I do treasure, however find myself today feeling very similar to yourself.
I could not believe when I read your post it sounds like the last few days I have spent at my parents' house. My Mum however is the one with depression and I do try and make allowances. I have listened to her moaning and complaining about everyone who is 'out to get her' over the last few days and then cannot believe the way she has treated me.
I have been there since Tuesday (just come back today) and we started off by watching a video of DS1 when he was a baby/toddler and I commented about myself being "at my worst" size/figure wise at one point in the video, to which my Mum turned round and told me that I was fatter now than I was then (I am a 14 now and was a bursting 16 on the video). She commented about everything I put in my mouth over the holiday, asking how many biscuits I had, when I replied, exactly the same about as you (she had been stuffing them in her mouth good style) she started saying "oh, are you counting the number of biscuits everyone is having now" to which I said "not really but obviously you are to have mentioned it". Anyway this went on and on, little jibes here and there about my weight, comments about the jeans I was wearing that they would be "worn out before I fitted into them properly again". I am still b/feeding my 7 month old and now feel that I am ready to tackle my weight, I have been attending aerobics classes since he was 7 weeks old, but this seems to account for nothing.
Anyway the final straw came as we were preparing to leave this morning, I felt she was pushing me out the house, and possibly feeing jealous that I was going to visit my bestfriend on the way home. She made a remark that I had been "having a nice time to myself leisurely getting ready", implying that I had left her with the kids, when this was not the case I spent 5 mins drying my hair (if I had not done this this would have been a problem also as you cannot in her opinion go out on a cold day with wet hair) and the rest of the time packing and folding the travel cot etc. She had been asking me on the phone previously about a jumper that I had and where I got it, I was wearing this jumper this morning and asked her before I was leaving if this was the jumper she was talking about to which she replied "yes but it used to be bigger on you". That was it I started, "the jumper is a 12/14 how on earth was it any bigger on my than it is now" (used to wear it in my bursting size 16 days as it is baggy) then said words along the lines of "this is great, not only have you examined and critisized everything I have put in my mouth over the past few days, told me that I have been bursting out my jeans and I have got a big fat bum but now my jumper used to be bigger" to which she said "I did not say you had a big fat bum" which was true she did not but she didn't need to, she felt it necessary to comment on everything else, including when I mentioned that my stomach way still quite baggy from DS2 (9lb 1/2oz I think anybody's stomach would be baggy) she said "I think it's all filling up with fat now". Anyway she was all ready to come down the car with my Dad, myself and the kids and all she did was hug the kids, and said a curt goodbye to me, when I asked if she was coming down to the car she said "I don't think so in case I say something else that's wrong". I can remember her saying since I was about 12 comments about my weight etc, and really I think she has alot to answer for any weight/food issues I have.
Sorry for butting in on your thread Girly, it's just it all seems so silly when I read it back but I am at present in tears and shaking when I think about it all, and I can't believe she thinks it is OK to treat me like this and no doubt it will be me who ends up having to say that I am too sensitive and apologise. My mum BTW has put on some weight herself since I last saw her and has aged over the last few years but I would never dream of mentioning it to her, and I accept her excuses that she needs to eat more chocolate etc because she is getting old.
She has also smacked DS1 on occasion even although I have asked her to leave that to me (I do use smacking as a form of discipline but try to limit the situations it is used in and feel that is for myself and DH to do). She has also spent the last few days saying how great DS2 is compared to DS1, and it seems everything DS2 does is so much better than DS1, to which I will agree that DS2 is an easier baby and probably an easier personality but the comparing of them was beginning to grate.
Anyway I think that is it all out, I didn't want to burden my friend with all this as she is just home from the hospital after having her second baby, and I feel a bit better now, sorry again Girly for gate crashing but I feel very much for you in your situation.
