I entirely understand. I'll be able to pick your brains as you'll be a few weeks ahead of me.
That site seems fairly balanced with many more success stories than not. I have a colleague who used their 'recovery week' thread - when you sign up, you are invited to it so that you can chat about experiences with those who are going through it at the same time. And the only people who can post on that thread are the moderators who have all been through it themselves so you don't end up with scare stories.
The site that I've also found very supportive - and overwhelmingly positive - is Reddit, if you're familiar with it, which has a sub on hysterectomy.
And, of course, here - but, 99.5% of women have no complications from the surgery... unless you regularly win the lottery or make a habit of defying probability, then you've nothing to worry about.
