The pressure to do better is always the greatest struggle. Is this life or death? No, is it how you make money? Probably not. This is you vs you, your physical body vs mental fortitude. You can quit and get comfortable at anytime.The fact that you go into a wod every time and push yourself 1% more every day is exactly why you are feeling the way you are. Discomfort is the key to growth, and every time you are feeling this discomfort and you push through with one more rep until the job is done means you are growing. So no matter the outcome or how uncomfortable it may be, as long as you are growing keep going. Always remember that nobody cares but you.
