It's been damn well worth it. That first picture is from the beginning of March. I weighed 181 pounds. I felt disgusting. The middle picture is 6 days after my last fight, at the end of October. I weighed 154.8. I felt pretty good, only gaining ten pounds back after cutting to 145 for my fight. The last picture is today, November 9th. I have a fight tomorrow, but my opponent wasn't going to make weight, so I didn't end up having to cut at all. I weigh 149.2. I've lost nearly 32 pounds in 8 months, and I'm pretty proud of that.
Looking at that first picture, I can hardly believe that's me. I'll never be that girl again. Ever.
All this took was a goal, some hard ass work, motivation, inspiration. I've had plateaus and setbacks, gained a few pounds back then kicked them to the curb, and I'm not done yet. I'm only 5 pounds from my original "goal weight", but the number on the scale isn't my only concern. I want beast muscles and my abs to show. I have more of a "look" goal than a number goal.
Whatever you do, if your not happy, change something. If you have a goal, chase after it with everything you've got. When you make progress, be proud of yourself.
