[T]his world would get so boring, and it's already hellish enough. Imagine never dying, and having to witness war after war, siege after siege, disease after disease, see people grow corrupt, destroy an entire civilization, and then rebuild it, and once it got things just right, it gets corrupt again and falls apart. Or then someone gets the idea to put you into prison, because you're in the wrong country at the wrong time. I mean, even if the woman you loved were immortal too---and you two had the most passionate romance ever---it'd grow dim. Unless we ourselves were empowered by Christ's Holy Mind, we'd never be able to accomplish it. Which is another reason we need Christ to go to heaven. As eternity in our flesh minds and living in this world would be the utmost worst possible thing we could ever have done to us. It'd be even worse than Hell.

Just ask Jesus to take it out of you. And keep asking until He does. If you need to, what helped me was blocking my access to my phone's internet. But then don't establish patterns on your computer, otherwise you'll have to get rid of that, too. Just cry out to Him to purify you. It'll work. 

Also, don't feel guilty about whatever dreams will come your way. All the saints go through that. Lewis, Augustine, Bunyan... if you built up patterns of lust, it'll come out in your dreamspace. It's unpleasant, but it's how it has to be. Don't be worried about stuff like "Succubi" or whatever. Literally, all the Saints had nightmares as that was the only place Satan could get to them. Just get up, wash, and stay out of battle until nightfall. Peace.

Buddhism is about removing desire, and causing yourself to not cause yourself or others suffering. It’s about “Empathy”. It’s about how your mind is not capable of understanding the outside world, and therefore, you are “Fire” as the famous sermon by Siddhartha goes. Everything is “Fire”, all things are rooted in your perception of them, including pain, relationships, joys. All things are tied back to your own perception and mental processes. It also has no belief about the afterlife, but rather views life as a cycle of reincarnations.

Christianity is about fulfilling your desire through seeking the Kingdom of Heaven. It’s about understanding the world’s suffering is arbitrary, and uncontrollable. That being good, you almost will have to suffer, but then you’re to find strength in God’s power and mercy, and joy in His Holy Covenant. It’s about accepting the outside world, and using faith to move “Mountains”, as in, accept reality for what it is, and shape your place in it by having the faith to endure and rely on God’s provision for your joy. It believes in reality… where Buddhism is focused on the interior world, Christianity is solely focused on the exterior world and your place in it. Its moral philosophy is strict, and prudent, and not about “Empathy” only, but also about repentance and turning away from sin; so Christianity is about discipline, so one has the tools to later find joy, and enter into the kingdom and not have sorrows. And of course Christianity centers around Heaven, and entering into the Kingdom.

[R]esolve to know Christ. Don't be indifferent to Christ. Pray all day, every day, meditate on His Word and commune with Him. No matter what, when you feel depressed, take a walk through a forest or desert--wherever, just like Jesus--and pray. You'll be invigorated. Tell God you're angry with Him, but don't let your heart be bitter, and ask Him for peace and love and to not be angry. Prepare to die for the love of your brother, and hope for his wellbeing and satisfaction more than your own. God will provide what's necessary for your fruit. As He wants love and peace, not style and cunning, developed in your personality. Every anxiety, go to the LORD. No matter how hard, go to Him, make known your true thoughts, and develop the fruits of righteousness. God cares more about that than your success. He'll give you whatever you need for righteousness, but prepare to suffer long for the hope of good and ripe fruit.

Do not worry. Ask God for heavenly treasures. And you will soon be freed from this world's burdens. You won't long for death, nor will you despair, but you'll have hope which is commanded.
