So Irritated and Discouraged

I cant believe this ! This morning the scale was up 1.8! Unreal! I dont have that much time to get it off before Saturday I dont even know why or how I gained it! Its been a good week! I thought for sure it would be down! Ate on points today and got in 30 minutes of weights and 20- minutes on elliptical! I just feel so discouraged right now!
