I am on a diet but I am having a hard time sticking to it.
Food is the hardest part when it comes to getting healthy sometimes. Dont give up! 
I won't but I am so desperate for good food.  I actually ate the leftover burger scraps off a plate at a restaurant the other day.  I am humiliated by it, but I really wanted a burger.
Omg! Okay now I understand how difficult it really must be for you!
