feeling kind of bad..

When I was younger, I was pretty thin. When I graduated high school, I weighed about 130 pounds. I wasn't "skinny" by any means, but thinner and healthy. When I got the college, the weight started to add on, but still, not terrible. I wasn't living in a dorm or anything, I was commuting back and forth from my parents house, so I was still eating relatively healthy. As I got older, more and more weight came on. My weight flucuated, and I'd randomly get into exercise and watching what I was eating. It seems like every time I start watching what I'm eating, my "highest weight" was even higher than it was before. Years ago, my highest weight was 145, then 150, then 155, then 157, etc. Now, after not one pair of pants fitting me, I'm back to wanting to lose weight. My husband and I just got married in May. I won't blame my weight gain on my marriage, my husband is very supportive, I guess I just got comfortable with eating whatever I wanted because I was so busy. I just started this past Tuesday, so I wasn't expecting a mircle already, but I feel like my hard work is for nothing. I feel no difference at all yet. I didn't weigh myself when I first started on Tuesday because we don't have a scale, but I can guessimate where I started, and was figuring it was 165. Well, we have a scale at my work, and I stepped on and I actually weigh 168. I know it's only 3 pounds heavier than I guessimated, but I guess I was hoping it'd be lower than that since I've been doing so good these past few days. I just get frustrated because I'm eating right (very different than even a week ago) and I've been doing Jillian Michaels 30-day shred consistantly. Sometimes I feel like this is all for nothing, so I guess I'd just like some motivation and to be told I'm being silly about being upset with no change right now. Thanks everyone!
