I WENT TO THE GYM TODAY!!!!!!!
 I know what you mean.  It's been hard for me too.  But I wasn't losing that much weight so I thought it might help me get rid of some fat and get some muscle.  I even hired a personal trainer to kick me in the butt.  So far it's working out great even though I have a love/hate relationship with him now.  I love the results (haven't seen much YET), but I hate the work and huffing and puffing.  I almost started crying the other night at the gym because I just felt so disgusting.  But I sucked it up and kept working.  One day it will pay off - I just hope it is soon! 
Don't worry - we all have issues.  Especially the ones of us that say we don't have any. lol
