Starting All Over Again for the Umpteenth Time

Sometimes I wonder if it's all worth it. Seems if I loose a little weight I wind up just putting it all back on and then some. They say it needs to be a lifestyle change, but I just don't seem to be able to put it together for the long hall, but ignoring it doesn't seem to work either. I weighed in at the Y yesterday. I'd ballooned to 350 lbs. So today I started the diet and exercise routine again. I worked out at the Y this morning and have felt like crap ever since. Tired all day today. Just keep plugging away I guess.
