Cake is yummy with Sugar

I just wasted 1.5 hours looking for a good bakery that can make a sugar-free cake. My dad is turning 60, and he is diabetic. Cake is bad already.. the sugar, the flour, the butter, etc. But it sure is difficult to find a place that can do a sugar-free one. So frustrated. So stupid.

Someone needs to open a low-sugar or a sugar-free bakery that makes cakes that tastes and looks good.

My written exam is set for the 18th. Stress has set in.
