Some are get very discrete symtoms over a long time, others can get really sick in just a few days... i had symtoms for a couple of weeks before diagnose. everyone is different.
really hope your bloodtests comes back as "not diabetes" but if you do have D, it's not as bad as one often hear

i've hardly noticed any changes in my life since diagnose
