You should educate yourself on the history of protest. The media has always been a serious impediment. There was never an "entire population" uniting or a "simple goal that others could get behind". It was always extremely difficult. It often looked hopeless. Many people were killed in the streets, and others were brave enough to replace them.
Overall I think feeling helpless in the face of monumental challenges is normal. But closing your eyes and telling yourself "nothing can ever change, so why bother" is self-soothing and pathetic.
Things can change, and you can be a part of that positive change if you put in real effort.
