There is no reason to believe anything in the media. Anyone who doesn’t suffer from Gell-Mann amnesia should know this is the right stance, it’s not even necessary to believe that it’s all propaganda to reach this conclusion.
Even more because you won't ever be able to verify every single piece of information yourself, you don't have access to all the data possible to verify it. You don't have access to people.
Again, you not trusting anything is the result of falling for propaganda that told you that nothing is trustworthy.
Are you going to reproduce every single scientific experiment to be able to verify them? Are you going to travel to every single place that has news about to interview people yourself and get your own conclusions? Nope, you just don't believe anything, you went to the extreme cynicism side.
It's impossible to achieve what you wrote, it's a lie you tell yourself because it's uncomfortable to trust, there's no truth except your own and that is... Very, very post-modern.
And this is the cynical post-modernist post-truth part that I criticise about your position. It's just a doubt of everything, of what's even real, and so you are just playing your part of the propaganda that made you think that way. The issue in post-truth is that your take is just another parroted version of "what's even real?". Even on this case, where it's pretty clear who are the bad guys, you prefer to be cynical and not even believe what your eyes can see.
You've been bombarded by subtle or overt propaganda your whole life, by governments and corporations. It's not by being cynical that you are somehow better than others or not being influenced by it, you aren't immune to it by believing nothing. Or by being a contrarian.
