Don't forget that Jesus loves you. Doesn't matter what you're going through, or where you're at. He's just a thought away. Rest in His peace, rejoice in His joy, trust in His strength.
He will pick you up, He will hold you, He will let you cry to Him. And He will love you more than anyone. When thoughts of doubt or suicide come into your head, just cry out the name of Jesus, and He will be there. He is strong enough to hold you, and if you listen to Him, He will tell you He loves you and suicide is not the answer. The only answer we have is Jesus. He is our all in all. There is nothing so bad that He can't help us with. We might be subject to depression or dipolar or whatever, but Jesus is greater, He will walk with us through this, and when we can't walk anymore, He will carry us. And when He is ready to call us home, He will do so, in His time, not ours.
And if we leave early because we can't take life, we might miss out on something special that Jesus has waiting for us here. So let Him do His job, and just believe in Him.

Well said!
