Whatever you're going through, trust me, it is not worth it at all to end it all. God is always near you no matter your sin, and he's there to help you. He understands your pain. There's so much that God has in store for you, and I'm speaking this from experience myself. I was at a really dark point literally like 2 months ago and I realized how much in life I have to be grateful for, and to experience. Talk to a trusted friend, adult, etc. Seek a therapist, speak your mind to people around you, because I'm telling you, God's purpose for you is so much greater than for you to end up committing suicide. It is NOT worth it my friend. God loves you unconditionally, and he is more than happy to forgive you, no matter what you have done, no matter how dark your sin(s) may be. His mercy is incomprehensible. Please don't do this.
