@Lufis You’re so awesome! Thank you for sharing that. Your question to “what’s the meaning of life” is a big one. I had an interesting experience with that. I was walking across my college campus one time and I heard in my mind/heart, “What’s the definition of life?” I believed it was God asking me. Throughout the week I kept hearing that same question, “What’s the definition of life?” I wasn’t sure how to answer. But then one day I found myself reading in my Bible, in John chapter 17. I got to verse 3, and here’s what it said:
“Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.”
I knew that the answer came right in front of me when I read that. I believe in God, and I believe that he was asking me that question all week to show me what life really is. And it’s to know him. Not just know about him, but to actually know him. God wants to be your friend. He wants to be your companion in life. He wants to be your Dad, and for you to be his son.
He’s a good friend who never leaves. He listens to you and helps you. He never leaves. And he’s a good Dad, a perfect one. He thinks you’re amazing. He brought you into this world thinking that the world would be better with you in it.
After you die, he wants you to be with him forever. There will be no more pain, and complete happiness and fulfillment. “Death” is just moving on from this world. If we don’t know God then we will be apart from him, but if we do know him then we will be move on and be with him forever, and where God is, there is everything good.
Even in the Bible the book of Ecclesiastes says over and over that “everything is meaningless”. That’s when you look at life without God in it. But with God everything has meaning! 
I visited Brazil too in 2012 and loved it there! I was staying in Campinas. I’ll also pray that you get to go to an ABR show!
I would say pray to God and he will show himself to you. If you have a Bible (if not just download the Bible app for free) I would recommend reading in the book of John and ask the Holy Spirit to show you what it means. And he will. It may not make complete sense right away, but something will change in your heart and you will start to experience meaning in life. You will see how Jesus lived as a human like us and faced all the struggles but didn’t mess up, and how he loved people like us. Because he really does love you.
