If you are overactive and always trying to lose weight, you may be hurting your body more than helping it. Always allow yourself adequate fats and sugars and do not lose to much weight at once. Sometimes your body needs rest too. Teenagers especially need to pay attention to this. You probably have had fewer demands, more positives, and are feeling more vigorous than usual.
Life is good.
This does not mean fewer demands or problems, but rather that your capability to deal with demands feels strong right now. The amount of stress you are experiencing falls into an average range. For most people this means they are doing very well, but occasionally feel overwhelmed by the demands facing them. It is likely that life feels less rewarding and more of an effort right now. You may feel less balanced, more frustrated, less in control, and more impatient.
