Vault prolapse operation has left me incontinent.

Help! Last year I had operations for rectocele prolapse, followed by cystocele prolapse and hysterectomy. These left me with a vault prolapse where the top of the vagina is unsupported and falling down. 3 weeks ago, I went privately to have a vault prolapse repair together with a TVT sling fitted.

I thought this must be the end of all my problems, but I am totally distraught because the last operation has left me incontinent. I am frantically doing my pelvic floor exercises (I did them religiously before the op) to try to gain control. I leak all the time and am now drinking less than I should to try to stop the leakage. It happens every time I stand up from sitting or lying. When I go to do a wee on the toilet, I only pass a little wee (about 30ml) but then feel myself wetting the pad within 2 minutes. I wake 2-3 times during the night and have a potty two steps away from the bed. My life is now hell - anyone got any suggestions?
