so bummed

So i weighed myself today. I thought I've been doing AMAZING. Lunges and squats (to the point I had to slowly "lower" myself to sit down for 3 days), TONS of pushups, back rows, pull ups, walking, etc. I even bought a Denise Austin work out video (I LOVE!) And my diet has been GREAT! According to the scale, I GAINED almost 2lbs!! WTF!!!! I'm thinking and hoping that it is muscle mass. I can see a difference in my body and in the way I feel, but I can't help but get super bummed about the number. My workout nazi will be leaving me to return home this weekend too. *shrug* then I will be on my own to motivate myself to keep up the work. we'll only be apart 3 weeks this time, I'll be going up north to see him this time instead of him coming down. yay..... freakin scale, I think I will go beat it with a baseball bat now......
