Feeling Frustrated!

My weight is not budging.  I'm doing what I'm supposed to do, but nothing is working... am I complaining? Yup.  I have stomach problems that are plaguing me and I feel like it's the reason I just can't budge.  Jen thinks I need to step up my cardio from walking.  I think it's a combination of both.  It's just so damn frustrating.  I'm so hungry after my workouts so it's hard to keep my head moving toward a goal.  I know sometimes I eat too much, but too much fruit and veggies? How is that possible?  How can the things that are good for you, keep you from getting what you really want?!  The days I eat a lot of fruit and veggies to stay off my hunger, my stomach problems act up even more!  I'll try to keep what the hubby says in mind, "drink water and wait 20 minutes before you go for something more to eat..."  I'm trying... did I mention that I read the Monica Seles memoir? I want to say, if she could lose weight, so can I, but let's be realistic...  I've been in such a mood the past couple days because I feel disgustingly bloated and in pain... why can't this be more simple?  I don't want to feel like these sessions with Jen are a waste... this week will be two days in a row with her, let's see some more results body!  ughhh... let me just be in my mood
