Not connected to mum and dad

Hi there everybody ive just been diagnosed  2 months ago with moderate to severe asd and i feel so stuck with what to talk about. My mother asks me how i am and i tell the truth im overwelmed with the world etc. It seems to set her off on the defence.  She hasnt been  supportive of the diagnosis  and i feel resentment  building. I have my wife and 2 kids 6 and 1 but my household so noisy i have regular meltdowns, i walk around with massive headphones all day at home which are really uncomftable. When my mum and dad come around i feel this horrible negative energy all of a sudden(i can feel their emotions) which makes me on edge.6 people  in my house at 1 time makes me on edge it feels so hard to deal with. Cant actually be bothered with this as it all drains me. I dont know how to communicate this. Nice to be part of this community to offload.x
