Hey, it really sounds like you're beating yourself up, calling yourself pathetic and loser. I've done it, and it seems to make the hurt worse. But I hear that's how you feel right now.

Don't ask people in the gym for advice. Research some good advice. With an intense-for-you workout and some food control, you can make quick gains/losses. One source of decent advice is "Body for Life" (a book). There are a few others that are realistic and practical. The worst thing you could do is get the advice of people who have always been fit and are just doing maintenance, or who enjoy being in the gym. So you are doing the right thing there, whether you know it or not, but not asking other gym users for advice.
