Hi i 63 and my husband has incurable cancer , he is 65 , i am stuggling with every thing i have no support , one of my sons lives with us he is 31 and is on the autistic spectrum. I am sat hear writing this at 4am as i dont sleep much as i have started to have panic attacks at night , i worry about every thing all the time i dont enjoy any thing any more , i feel like i dont want to be hear any more , i dont want to watch what i know is coming .
