I don't wish to give up, but I am tired.

Right now, I am in a period of a lack of motivation.  Giving up on exercise seems so easy now.  However, I am frustrated and I won't do it.  What is the use of buying equipment if I don't have the motivation to do so? I just don't feel like it today, but I won't complain.  I just have to go out there and just do it, right?  I guess that is the only way I can stay healthy and lose weight.  Why am I like this?  How could allow myself to lack the motivation that I so need?  The last time I exercised was Monday.  Despite my health risks, I have to go our there and just do it.  I have gone too far to turn back.
