I tend to feel really hopeless whenever I browse this site, and several days afterward too. But, I find something that really helps is (and this is going to sound bad but let me explain) just not give a crap, at all. If it's bothering me to the point I can't focus on anything or enjoy any sort of media at all, that's a problem and I need to not care about what ties or connections or horrible abuse some musician might have and just focus on what's presented to me. Doesn't mean submitting to the illuminati/satanists, it just means keeping me sane in the moment. It got so bad at one point I was honestly considering blocking an online friend of mine because she made a lot of the 666 hand signs in her photos, which this paranoia is something I had thought was crazy just a few days prior to experiencing it myself. I may not know 100% that she's not a satanist, or an mk/monarch slave, or part of the illuminati, but there is literally no reason for me to think she is. After separating my fear from the rational part of my brain I just had to laugh.
Plus, sometimes, like some other said, a triangle is just a triangle. Or maybe it's not. But sometimes, especially with not as well-known musicians/music video makers/photographers/etc., if there's something sort of esoteric in their creation, I personally believe there's a fair chance that it's just mimicry. It's just following what's popular or trendy, or just trying to be spooky. Or the person could even be one of those "tin foil hatters" like us, and trying to recreate something they know. (A friend of mine was so mad a few days ago because a musician she REALLY loves has a music video where this girl discovers this triangle in a tree and then goes on some sort of drug trip with some bearded wizard guy in a black robe. She thought it was indicative that the musician is a satanist/part of the agenda but honestly I told her that I don't think so, because 1. he's not very well known except for maybe 2 of his songs, 2. the music video was not directed by him and he had no input, 3. the director isn't well known (and looking at his website there's nothing about it that screams "satanist" to me, + he has a detailed description of the music video and the description reads like a guy just trying to sell his idea and the "cool" part of it, aka how it looks--it's a really pretty music video), and 4. just like with the case of M83's "Moonchild" music video, I think it's merely a case of mimicry. (Though that MV is definitely more questionable, seeing as what the name of the song is, and how everyone in it is just staring at this painfully bright glowing triangle on top of what I think is Hollywood Hills, and there's yet another guy in a black ro--wait...)
Speaking of friends, if you feel you can't trust any media, at least you can trust your friends...hopefully. You should only make friends with people you can trust anyway, but my point is, talk to them. Let them distract you from the evilness in society and this world. Go outside and enjoy nature. I went on a walk with my daughter and hubby just the other day. It was pretty cold but there's nothing more healing for a scared soul than the peace and safety of the outside.
...Unless you live in bear country. Then it's probably not so safe. Maybe bring some bear spray?
