Life won't ever be the same again @Me2 and no amount of motivational memes and happy clappy statements will change that. It's so hard when you get rocketted into the really tough stuff so quickly with no time to prepare--its just awful to feel cornered. No one chooses this path.
It's been a month for you now, and you've come a long way. Another couple of weeks and the surgery will be over. I don't think we ever stop worrying, but the focus changes. Sometimes the really big things are easier to deal with than stupid little details, our brains are remarkable things.
Keep going, it won't be all bad news (though it may feel like if sometimes) Your turn to help will come. You are already doing that. Someone out there will be reading your posts thinking 'Its not just me. Maybe I'm not losing the plot after all.' xx
