Bad Week, I'm Loosing My Grip

I don't understand how I haven't lost weight this week. I've been under my caloric goal each day and I have been exercising every day as well. In fact I've GAINED weight for some god awful reason and I'm starting to move beyond upset and into very angry and pissed off. Now my chart says projected date of goal completion (10 pounds lost) is April 12th instead of March 24th-31st!!! I CANT go into April! I am on a tight schedule! I want to go swimming with my daughter this summer and actually be semi comfortable! If I don't loose the weight I can't 😖

I don't mean to be such a downer but I'm super depressed right now. I don't know what to do.
