Setbacks...I am used to these

I have had a few setbacks recently.  I was doing good with my workouts and then I bent over to pick up my baby and feel a bad tweak.  My back was whacked out for the next 3 days.  Then my cycle started and that came with some debilitating headaches.  I feel like these are horrible excuses but I know they are not.  It is hard to work through certain types of physical pain.  The only thing I can do, is get back to it and not get discouraged.  Not working out has led to some psychological side effects.  I am having a hard time feeling motivated, positive and have been feeling very depressed at everything.  I have a horrible body image right now and I want that quick fix but that is not gonna happen.  It took 8 years and 4 kids to get to where I am at and it's not going to change overnight.  I want to feel sexy, I want to feel desirable to my husband.  Don't get me wrong, he loves me no matter what and has told me that more than once.  I am the one who feels undesirable and disgusting.  These are things that I know I can combat, it just takes time and effort.  It's time to stop being a lazy ass...quite frankly!!! I am starting again on Monday and just going to make it through the week, one day at a time, each one is a victory.  I just gotta keep trying because each time I have to start over, is better than doing nothing at all!
