a little frustrated

So this morning I got up and got on the scale I was feeling frustrated cause I worked really hard all week and only seem to do be down 3 pounds or so, I know its only been a week so I measured myself, and I seem to be down around 10 inches so thats a good things right? I wish the weight would just come right off its so frustrating.  Its easy to get on but a pain to get off.  I have my trainer today so that should lift my spirits up.a bit more.  I guess when I started this program I thought I would be down all this weight right away.  Im doing pretty much everything right.  I guess we will wait and see....
