Doubt I'm gonna make it to 18 yrs old

When I was sixteen I made a fifty dollar bet with a printer of early middle years that before my 50th birthday I would die because nuclear war would erupt in the Middle East and then spread to the rest of the world. Unfortunately when I reached age fifty I was unable to find him to pay him his winnings. Almost 20 years after that I still acknowledge that I own him the money.

My point is that you are probably wrong. But then again . . . maybe not. Best of good fortune in future decades.

Are you involved in a church? If not find one that teaches the Bible and go to the youth group (it won't won't be a Catholic, Methodist, Lutheran etc.--see if you can find a Calvary Chapel or similar non denominational). This will give you a solid source of truth, turn off the lies on social media and the world still sucks, but you see past the negative garbage.
