First off welcome to Cerb:)
and as everyone probably feel, I am truly sorry about your condition, learning this whatever age you are is extremely hard.
As for being on Cerb, it is a good place to be, as you know you will not be judge by people, whatever your physical or mental condition is.
You may want to tell if you are looking for an SP(service provider aka escort) or an MP(massage provider). if you want to do incall (visit the SP at her place) or outcall (the SP travel to you). what type of services you want (gfe, pse) and what type of body, personality if you have a preference.
Also looking at the recommendations in the Ottawa section can give you a good vibe of what type of service/person the lady that you may have an eyes on offer. Try to stay away from BP and DL, some reputable ladies post on it, but you have a little bit more chance to get scam then sticking to the ladies on cerb...
and most of all...good luck in your search and I truly hope that if you have the chance to see a lady before your condition get worst, that you have a really good experience:)
