How I feel about losing weight

I am reminded of the benefits of weight loss and exercise.  I wonder if weight loss is a rocket science.  Why is it so hard for me to lose weight?  Weight loss is supposed to be hard, not easy.  I feel like giving up, but I will stay.  I am reminded of all of the times when I have lost weight.  I feel like I have been hit with reality.  I don't want to weigh what I weigh right now.  I have gained a few pounds since last week and all of the times that...I don't know.  Despite exercising this morning, I just want to give up, but like I said, I won't.
