Concerned for Friend

So my friend is going through a hard time and has a fixation on thinking he's hacked, and has for about 2 years. It has waxed and waned in terms of the severity of the obsession.

At one point, I think he was legitimately hacked, but he no longer has the computer it happened on and it was years ago.

It's gotten worse again and he's sending me "proof" but when I research it, it appears to be just typical stuff, but he has spent years looking into this stuff so he doesn't listen to me.

Would anyone on here be open to like.... Looking at things happening to him and see if it's legitimately hacking or if he just needs other kinds of support?

He's thrown away multiple phones and computers thinking they're hacked and he doesn't have money to throw at this type of thing. He also totally wiped and got a new motherboard for his computer, and just got a new lap top hoping it would be different but he's thinking it's happening there too.

I'm very very worried about him... I can provide picture examples but it won't let me here for some reason.
