Is this really how I'm suppose to be?

I'm at a loss and it isn't a good one, the only thing I seem to be successful at these days is gaining weight. I'm not over exaggerating this by any means, I seriously am gaining about a pound every week. And don't tell me oh that means you are eating 500 calories too many each day, WRONG!!! I really have no idea what to do. I'm so tired, tired of wasting my time, effort, energy and money only to have my pants get tighter and tighter. I'm exhausted, I can barely get up in the morning, I try my very best not to fall asleep at work everyday, it takes everything I have to make it to class after work and then walk my dog when I get home. To be honest failure every week is down right depressing.

If I were told this is the weight I'll always be at no matter what I do, I would accept, I may not be happy about it, but I would accept. I'd go out and buy new clothes that fit, I'd get rid of my scale, HRM and everything else that brings me down. I'd workout just the same as I do now, and I'd do a little more ST so perhaps I could at least have more muscle and feel healthier.

Is it suppose to be this hard to lose weight? It seems like such a piece of cake for others, eat a little less here, have a little more of this and just like that they lose weight and their clothes fit better. Do I have to starve myself for the rest of my life in order to not gain weight because that is truly how I feel at this point and I've gone out of my way to not live like that. What will I tell people when they ask what I do, oh I starve myself everyday and workout like an athlete you know the usual. No, I don't think that's what everyone else does, but I've begun to wonder.

If anyone has any suggestions I'm open to them, surely there has got to be something out there I haven't tried? Just tell me the secret already!
