Motivation?

Ive been laying in the same spot for the past two days.  Im suppose to be active and aiming to loose weight during this summer. But for some reason Im not motivated enough to get up and go.  I have no one to accompany me to for a walk or to the gym.  I think i need new motivation.  Maybe a pet so I can at least carry it for a walk so i get my work out that way.  Cause its coming to the point in my life where i am getting lazier and lazier. But heres the other problem.  I dont want a pet.  Well I do.  But i have a tendency to go away to another city sometimes and for a long time.  So when i leave who is going to look after my pet?  Ahh so I am back at one.  I need  motivation.
