I have to start going to the gym. I promised my partner I would, and I myself want to lose weight. 

Do I like exercising? No. 

My question is, I’m so miserable every goddamn second of the day that when I have free time my brain always thinks, why spend this doing something I KNOW I’m going to hate and make myself more miserable? And then I don’t go. 

How am I supposed to motivate myself when I have no energy or willpower to improve things?
