Nervous about vrs

So long story short I'm hard of hearing and not able to speak due to other health issues. Im an ASL 5 / 301 student with Canadian hearing services as well. My question is this does anyone know how patient VRS (Canada) is with folks who are still learning ? Or are late deafened ?

I've mostly been sticking to IP relay for 90% of phone call stuff or using web chat , email or Facebook for other 10% because my voice is totally gone.
