Apple watch not working

Had it in swim mode, took it out of swim mode, and seemed fine. hour later, got the charge symbol and just the time. Put it on charge, went to apple sign, would not charge. Did the pressing of the two buttons, went black, then went back to the charge symbol and time. Still would not charge. left it on the charger for 10 hours, seemed to be okay. I was able to do the apple update, but it took about 2 hours. The battery died again in 3 hours, then the screen had white streaks through it. Finally went back to the apple sign, then to the charging sign with the time and has not moved since.
