Frustration

Assalamalikum girls,

ok so I just need to vent and get out my frustration after just speaking with my mother.. it isnt any backbiting just annoyance at how she is acting. Its been 5 weeks since my grandmother died, and just over 4 weeks since she was buried.. so that means just under 4 weeks since I have been back in Canada. The day I arrived back my mum had organised to go to a neighbours bbq and dragged me along.. well basically she was there when I arrived back at her house. She left early on the sunday for a christening that I had been invited to (alhamdulillah, I didnt want to go) and I left to go back to my place before she got back that day.

I have seen her once since then, partly due to my own issues of not really wanting to be there while Im fasting. But I went up last weekend, she was at her 'friends' (yeh I dont really like this friend of hers, she takes advantage) She didnt intend on coming back to hers, even though she had known for nearly a week that I was coming up, I stayed under 2hrs! This weekend is the long weekend for thanksgiving and Im also not praying so I thought I would spend the whole weekend there. We intended on going to a big market town called St Jacobs and I phoned her this morning to tell her i didnt want to go on the saturday as Im working till 11 on the friday and it opens just too early. So then she tells me she cant go on sunday because we have all been invited to her 'friends' for thanksgiving dinner (her friend is english just like us!) I dont understand why she keeps breaking things with me and its hurting me because all I want to do is curl up with her and for her to tell me everything will be ok :( oh look.. Im crying now, such a baby...

I understand shes having issues at the moment with her up and coming operation but why does she have to spend all this time with her?? shes babysitting during the day for her and wont take money because they looked after the dog while she was last in hospital, for 6days they looked after the dog.. the woman has 4 kids!! and my mum has been lookin after at least 2 everytime shes been there.. subhanallah.. shes not well..

Am I being over reactive??Am I being selfish? Or am I being stupid?
