In October my family and I were hit head on by a drunk driver. I am a mother to 2 and a stepmother to 2 so we have 4 kids total ages 10, 11, 12, 13. The kids had various injuries but are now back at school and doing quite well. My husband had leg injuries and it will be a few months before he is back to his normal routine. I had a TBI and have gone to neuropsyche for their batter of tests and have issues with multitasking and memory. Being cooped up in the house is extremely stressful but when I go out I get tired easily so it's like a double whammy. My sister in law has come from another state to help take care of everyone. I have also been dealing with an inept neurorehab center and don't have an appointment until March even though we have been fighting to get one since the accident in October happened. I have been told by various physicians to ease back into doing normal things and when I try , I seem to step on other peoples toes in the household. I am finding that I am increasingly angry and frustrated. I'm angry because I am stuck in the house being told to increase what I do yet my husband keeps giving my sister in law all the tasks. I feel like I have no one to talk to and just keep getting told that I am having episodes of frustration. I can list out what frustrates me ranging from the facts that I get tired easily, I am stuck in this house, I can't drive, anxiety over taking everything back over when my sister in law leaves because now the stepkids think she's the most wonderful person on earth and fall all over themselves to do chores for her when I used to get the "cold stares" from them when I asked them to do their chores with a few "you're not my mom!s " thrown in. My anxiety is huge when it comes to even the thought of her leaving. But yet she gets frustrated when i get irritated after I have dealt with 35 different people on the phone trying to get a neuro rehab appointment and then finding out they didn't schedule it until March. Drama she calls it. My husband just sits there and I can't really remember the last significant conversation we have held.
Anyway, I would like some outside advice on how to deal with the every day frustrations. If I feel like i'm starting to get frustrated over something I am doing or something that is not going the way I think it should, What should I do? should I extricate myself from it immediately until I can think about it rationally and what kind of phrase can I use to clue my family in on the fact that I need some time to think about things?
thanks
