Many people do extremely well if it is diagnosed early. On average on average after 5 years of illness , over 80% of people have survived. How they do is strongly related to the severity of their illness.
I personally live pretty much a normal life just as I did before I became ill. Of course it took awhile as I was very ill when I was diagnosed . It is of course important to maintain your medical treatment and keep as normal as a life as possible . It does get better in time. I am current I remission and have been for the past year. I still take my medications regularly and see my doctors on a regular basis.
