Sad For Gained Weight

I am so sad with how my short insanity made me gain weight. It's the butterfly in the stomach and the crazy waiting on nonsense messages. But I am so back on my feet now.
Funny but I gained weight but my clothes still fits on me the same as usual. I guess my exercising helped me to maintain the level of my fat in my body. However, I still need to lose weight even if my clothes aren't tight on me.
