Rant away
It's just awful. You will get through it though, and take all the support you can because it can make you feel very alone. You'll find a few on here who have been through similar who can support you. Just give them time to find the thread.
Post repair surgery was pretty scary for me too, I remember looking like I'd been beaten up down there.. But two years on I have had another child (c/s obviously as the reapir took away the necessary stretch for birth),and even have sex once in a while when I'm not so knackered I can barely speak
You have to be prepared to fight for what you need, and reading that thread I recommendeded, and asking others on here will give you clues as to what help or procedures, you aren't being offered.
I wasn't given the option of a GA with the cortisone injections. I did ask for a pre-med or valium, but again didn't get it; they said the anaesthetic was in the injection - but it takes half an hour to kick in (and then covers you for about 12 hours) and it's obviously the injection itself you don't want to feel! I would ask your GP to prescribe something in advance, which is what I should have done. Also check out my comments on Instillagel as a tube of that administered before you go might help to numb a bit too.
It is painful to have done, but it dissolved a lot of scar tissue for me. Unfortunately I just had too much hence the Fenton's.
I so understand what a dark place you must be feeling in right now and am welling up now remembering my own problems, but try your hardest not to let it in to your head and stay purposeful, you will be better. Maybe not as perfect as before but I know that feeling of being "ruined" down there and it's honestly not like that for me anymore.
Anything else you want to ask or talk about I'm here.
