STAYING MOTIVATED - Help!!

I need friends - preferably non-skinny friends - that want to commit to exercising or calling or exchanging recipes and most of all that like laughing together more then any of the above.  With our busy lives it seems next to impossible to coordinate a time to work out a schedule with someone and yet I'm not good doing anything alone much less something that needs me to make so many personal changes in me!  So what do I do?  Where can I dig up some friends?  Where do I go to find someone that wants or needs the things that I do???   Any suggestions?
