Hi Ann
welcome to the forum, and well done for finding us and plucking up the courage to post so quickly.
It took me ages - but this is a very friendly place and you will find some very well informed and helpful people here.
You must still be is a state of shock. I know I was. Even though I new my eyesight was changing so suspected something was wrong it was still a huge shock and I am sure no one here will be at all suprised that you sound a little panicked.
In truth I cnnot answer your questions - time from diagnosis to various stage points seems to vary hugely dependent on a number of factors - age, severity at time of diagnosis, ability to tolerate contact lenses, sight achieved, luck,who you are seen by, the list goes on.
I have been diagnosed for about 7yrs and grafts have not been mentioned yet (except to say I may need one in the future). I have KC in both eyes - right more than left - but can still drive, manage my job and mostly carry on as before - Which is not to say I am unaffected or that I don't get scared and upset sometimes.
There are others here who are far better informed than me, not least because they are further on this journey. Listen to what they say and take both warning and comfort from them. However your experience is your own and you must follow your own path. Some will recommend surgery, some lenses and some will suggest more interesting and unusual possibilities. I will only recommend that you read, consider and decide for yourself.
Sorry I cannot be of more help - and now I will get out of the way while those with more useful information swing into action
