Why Am I So Tired Lately?

I've started moving more,
Zumba classes & walking.

I've tried to choose better food options,
tuna salads, low fat, portion controlled meals.

I thought I'd get more energy.
Instead, I feel tired.
I go to bed early
(cause my eyes are closing on me.)
I have been getting sleep
(albeit not a full night's rest at one time,
but I sleep nonetheless.)

I have a lot of stress in my life,
I believe the addition of exercise
will help me better cope with and
reduce the stress level.
Stress won't go away, how
I cope with it will help.

I'll stick with it because I know I
am making positive steps but I
just want to begin to feel that difference.
