..... lost my dad February 2010. Thought my mum would die of grief. They had a loooooong and unusually happy marriage - did everything together and were full of affection for each other. We've all rallied round over the past year (me, my older sister who has moved in with my mum, my brother, and my mum's friends) and tried to keep her going, though it's been difficult at times. She's had bereavement counselling and is no longer crying on and off all day, every day.
Over a year on and I'm not expecting any *massive changes. They were married for nearly 50 years and I know she's never ever going to 'get over' losing him. But I'd hope for a very, very gradual increase in happiness. And this seemed to happen for a while. Her physical health improved, she started to go out more. Things appeared to be slowly getting better.
However, over the past few months she seems to have gone through a personality change that's making her incredibly hard to be with. She's very bitter and touchy and critical, to the point where I've become wary of saying ANYTHING to her that isn't 100% positive. An example of this would be the other day when she made me a sandwich while I was visiting her. Her eyesight is very bad and I think she didn't realise that she'd totally overloaded it with salt, to the point where it was actually making me feel ill as I ate it. She said 'is your sandwich ok?' and I said it was, because I felt that if I told her it was too salty she'd get angry with me. Later I said to her that if she got an electrician in to check one of the dodgy light fittings in the kitchen he might suggest she has some rewiring done. Her response was a very ratty 'Yes - I know that'. She's terrible with my youngest, who is five and has ASD. She's very controlling - over silly, pointless things. I mean it's literally non-stop telling off and instructing. And he's really not that bad - a bit silly and hyper sometimes, but not destructive or aggressive or anything.
Last week he accidentally broke a cheap, narrow bottomed vase she had on the floor by the front door, while taking his shoes off. It was a complete accident - I was watching him and saw that he wasn't being silly or careless. She immediately said 'Now look what you've done!' and when I responded, 'mum - it was a complete accident' the response was 'yes, but he's always doing things without looking where he's going'. She then repeated this to him. He was very upset and started to try to pick the glass up, at which point she got angry with him for that too. On the way home he said that she'd told him that she'd had the vase for 10 years. He's 5 for goodness sake. And even though he'd said (and I'd said) sorry over and over again, she had to wait until I was out the room and then guilt trip him. 
I know I ought to see her more (it's an hour's drive to hers and I usually go once a week and talk to her on the phone every day) but I feel an intense reluctance to that I'm finding hard to overcome. Recently I've gone a fortnight without visiting and had a few days go past in the week when I haven't called. I feel that I'm constantly walking on eggshells when I'm with her, just waiting for her to snap at me over anything. And she does snap and gripe and take umbrage at everything.
And I HATE taking the children over because of the way she's been behaving with my youngest (even though I know she adores him and also gives him lots of hugs and kisses). I go over there with him and just feel so stressed and tense.
I'm wondering if this is a permanent change of personality, and if it is, how are we all going to cope with it. She was very angry for a while in the first few months after my dad died, but that anger wasn't directed at us and the rest of the family.
Any thoughts? (ps - know I should have put this on the bereavement board but usual excuse - it's busier here!)
