Hello lovely MNers :)
Over the last 3ish years, I have kept The Brave Babes threads running in Relationships (because that's where the first thread was posted and with very good reason) from the first few threads that were posted for purely selfish reasons. To keep myself sober.
Whilst the threads help lots of posters to get sober, stay sober or change the way that they drink, the threads also help lurkers.
Those who are perhaps a little scared to say out loud "I drink too much and I'm worried about how I feel about it....." or don't know where to start.
We have regular MNers who NC because they don't want to be 'outed', they're scared and terrified of what might happen once they say "I think I'm an alcoholic" and someone says 'Oooo, hello I know you Mner' 
We have MNers who maybe only post the once, or a few times and then go. And then we have MNers who are still on the Bus every day, trying to stay sober, stay in control, stay bloody sane! 
For me, MN is a lifeline. My darling son has Complex SN, and the SN Children threads have given me so much support even though I don't often post, and so they don't really know that they also help me so very much. I read them. I cry, laugh and nod. Lots.
There are a number of posters who I admire beyond all possible admiration, for keeping going after losing their precious children or loved ones, being abused and surviving, losing so much of themselves, losing the lives that they thought they would always have.
The posters who had nothing but a mobile, a bag of clothes and their children. Those who needed to run, before 'he' came home. Before 'he' came back to abuse them. Again.
I remember weeping at some of the posts about abusive relationships because of my own experiences.
I remember the day I learnt what a Mooncup? was and ordering one, unsure of the best size and having to ask 
I remember the 'We Believe You' campaign because I was part of it, on the front line so to speak.
I remember the lost toy in Blackpool thread was amazing.
I remember Trinity's horrific loss. The numbness in her posts. She's since been one of the Bravest Babes I know and I admire her greatly for the way she has turned her life around following such a cruel and twisted diversion put into her life.
There are SO MANY MNers who have touched my life, I mean really.
They've become a daily part of my life to ask how I am, how my pain is, where I'm up to with my meds, how Nemo got on in PICU, is he home, texts, calls, visits FFS, MNers turning up on my doorstep to help me out with something
I have had presents sent for Nemo 'just because' he's been poorly or not quite himself.
There are too many wonderful Mners who have kept me going to mention in this post but I have laughed until I needed a fresh TenaLady? and I have cried until DH has said what on earth has happened with utter horror in his voice thinking that the absolute worst has happened, and on here, it had.
But I have smiled until my face ached 
There are posters who got out of violent relationships and survived. Just like I did, I wish I'd known about MN then, when I was being raped, abused, beaten, used and attacked.
The support on here blows me away. Each and every day.
At Christmas, I spent days crying as more and more wonderful boxes of gifts arrived each day. I had no idea that people cared so much about my family, my darling boy Nemo and my wonderful DD.
I've met MNers in real life, I have forged so many strong, real, lovely and true friendships from joining MN.
What does Mumsnet really mean to me?
Seeing people survive through the darkest times in their lives because of the kindness of strangers. People helping, driving miles, delivering a teddy, food, money, Wolly Hugs, getting someone to a safe place, holding a hand, fighting a corner, and even taking about Yoni massaging
That is what Mumsnet means to me, in the shortest possible post!! 
Thank you HelenMNHQ et al for being who you are, and letting us be who we are too :) xx
PS - sorry for any typos, I'm shattered after a long day of playing with the boy. Sorry for the long waffling post and thank you if you read it :)
