Dreamy thank you 
State I had a brain aneurysm aged 16, was told I'd never be able to give birth naturally as it was the unknown and no medical professionals would be willing to see what would happen with the pressure on my brain. Same advice aged 25 having DD. 9 Years on, advice has changed and if you had your aneurysm 'clipped' there is no evidence of vaginal delivery causing harm, when assistance is given and mother is monitored closely (assistance being shortened 2nd stage labour - no more than half an hour pushing, then use of forceps)
I understand my mum's pov, i really do....but I also know that there is no way on earth the Consultant, Registrar and the Neurolical team would let me have the VBAC if they though I was at risk - they wouldn't do it for the fun of it.
I have a 9 year old, I want to be back on my feet asap after the birth, not dependent on everyone else (this has been my bugbear recently, my loss of independence, stupid but true!)
The Neuro team have yet to say yes, so they may actually insist on CSection, in which case I will happily go along with it as I know what happens and DD was a very positive experience.
I just need my mum to stop offering an opinion based on her fears (which I DO understand, I am her child, I get that!) and realise I am a grown woman who is taking medical advice and not just making a rash decision because I feel like being awkward! rarrrr.
As for your fears - totally normal, I remember having my date confirmed (23rd Dec) and the run up to that, the last week, I was convinced something awful was going to happen. It didn't, of course, but I coudlnt shake the feeling. with your family history, it is even more normal for you to feel a bit vulnerable ((hugs))
