I've turned fat!

Since I've hit my lowest weight ever, I ended up gaining six pounds! I know that doesn't sound like much, but my body is very responsive to what I do to it, and lately I have been eating not so well... and six pounds definitely make clothes feel a little tighter and the face a little chubbier. However, I am not harboring any negative feelings toward my weight gain... I'm actually truly happy right now becauase I know that this is the day I have to go back to taking good care of myself... Plus, all the foods I ate to get to this point were soooooo good, why shouldn't I be happy??
