For what it's worth, I was diagnosed at 19 and was a huge basketball player!!! Major kidney problems was what I presented with. After I was diagnosed, I had a few crazy months of getting meds on track and struggled on to university for my first year.
I began feeling better when the weather got colder and was back in the gym playing anything I could. Sick the next spring, recouping in the summer of the following year, I tried out for the varsity basketball team in my second year of uni. Although it was incredibly hard for me, it was a huge feat and it kept me going!!! Looking back now, I can't believe the things I have struggled through but I never would have had it any other way!!!
Don't hold that girl back!!!!!!
(Ps, it's now 20 years later for me)
