First off, take a deep breath, and relax
Did you do it?
Ok, now then. If we all could simply decide to not be fat anymore and we woke up skinny tomorrow, forums like this wouldn't exist. Nobody got fat overnight, so we're not going to get unfat overnight either. It takes hard work, and yes, time.
How much time depends on the individual. You've said in other posts you weighed 205? You can safely lose 1% of your body weight per week. So, first week you can lose 2.05lbs, next week you can lose 2.03, week after you can lose 2.01 - see, it goes down as you lose weight.
If I run the numbers for you in an excel spreadsheet, And you are very committed to losing weight (its hard to lose weight properly at 1% per week), you should be able to lose 50lbs in just about 28 weeks. Thats about 6.5 months. You'd have to start out eating 1000 calories under maintenance, and by the end of the 6.5 months, you'd have to be eating about 750 under maintenance. Keep in mind, maintenance level is going to be constantly changing as you lose weight and your body adapts to lower calories. And this is not "going crazy" with diet and exercise, this is simply creating a calorie defecit from your maintenance level.
6.5 months is a long time. But, the time is going to pass whether you're trying to lose the weight or not. You can spend the next 6 months getting to where you want to be, or you can sit around feeling depressed about it and doing nothing and being no closer to where you wanted to be than right now.
I've got an ambitious goal to get to 260 in the next 10-11 months, and thats still not going to be anywhere close to a goal, and thats assuming I can stay fully committed for so long, which is going to be tough if not impossible. And thats assuming I don't hit a stall. And thats a long time to imagine, but the time will pass either way and I'd rather to be closer to a goal in a year from now, than be where I am right now. And when I think it might be 2 or 3 years at least before I actually no longer look flabby and start to see some muscle, I can't even compute that time. Maybe I should set a goal to see some abs by the time I'm 30? 4 years away seems like a long time.
Thats why we set smaller goals/milestones. You could get under 200 in 2 weeks! that would be a good first milestone and would be very motivating. Then shoot for 190 in 5 weeks after that. And so on. My first milestone is 350 by the end of july. Then 330 by the end of september (330 was the weight I sustained for 6 months after my wedding before having medical problems). Then <300 by the end of the year. And then finally 260 by sometime in May 2011. But whenever I think Man, I want to lose like 100lbs and its going to take me almost a year to do it, its disconnecting and discouraging.
So just relax, you want to live healthy for the rest of your life. 6 months or even a few years you took to get healthy will not seem so big when you look back 10 years from now. I'm only 26, and already my HS and college years don't seem as long and daunting as they seemed when I was living them. The same will be true post weight loss. Once its in the past, the amount of time it took to get there will no longer matter.
Cheer up! We're all in this together
