If you're frustrated that the scale isn't moving as fast as you'd like, don't assume that you must be doing something wrong. That's just not true. While a safe weekly weight loss would be 1-2 pounds per week, there may be weeks you don't lose. There may even be weeks when you gain. And that doesn't mean you're doing something wrong. Weight loss is a slow steady process that takes time. Remember, there are changes happening to your body you can't see.
So, don't beat up on yourself because you're not seeing a loss like those on the Biggest Loser. those types of losses are just not typical.
Now, if you're feeling frustrated because work is stressful, home life is stressful, school is stressful, relationship is stressful... you do the best you can. You're not Wonder Woman. There is only so much a person can do. If you seem overwhelmed. set your priorities. What IS the most important thing you want to do ? Then you sit down and decide how you're going to achieve that goal. Everything else goes on the back burner.
What is it that's bothering you ? Maybe if you blogged about it, you might feel better. Blogging and writing can be very cathartic.
