<human>: Can you give me the gist of the text in a nutshell?

My childhood friend from third grade to eighth grade is severely depressed, and I want to reach out to him, but I don't know how to without sounding creepy or intrusive. The only reason we aren't friends anymore is because my family moved, but we used to hang out every weekend during that time. We are friends on Facebook, but haven't really spoken since ninth or tenth grade (I'm a junior in college). I will say that I tried to contact him throughout high school, but he's not really a social media person, so he didn't respond to most of my messages.

Anyway, our parents used to work together which is how we became friends and they're still in contact with each other. Our parents still talk a lot and they've expressed concern to my parents that their son is depressed and they kind of hinted that I should reach out to him. I want to reach out to him, but how do I reach out to him in a way that's not completely awkward? I haven't talked to him in a while, so I  feel weird texting him in the middle of nowhere, "Hey, ___ it's _____! Long time, no speak! I hear you're depressed! Need someone to talk to?" I'm just looking for advice on how to reach out to him without making him angry with his parents for talking about his problems with people. Should I just say, "hey! it's ___! how've you been?"
