We can win, but we do need to focus our energies, & not indulge in comforting fantasies. (e.g. "someone else" is taking care of it).
Imo it's wise to give the bulk of your online attention to those who offer concrete practical steps, however small they may feel or seem. Join those who are taking action to help others, in any small way. If that feels too much today, believe me I get it: then do something to help yourself. Slice it thinner until you find yourself moving in a healthy direction.
