I think this is a very pessimistic way of looking at it. I completely understand where you are coming from because I have gone through this exact feeling of hopelessness and I still do sometimes. But if you hold on to the idea that it is a "battle you cannot win", you have already lost. While no one can force you to take up your battles, you shouldn't force yourself to give in either. You can do wonders if you believe in yourself. Belief is half of healing.
