Hm.
Well, it'd be easy (and probably save me a lot of time - emotional hot button, personalized, threads are always the ones that become the most consuming) not to respond. But you are a pretty straight shooter and you deserve the respect of having me return the favor.
1. All humanity is naturally headed towards hell because we are sinners, and that is what we choose. You, me, e'erbody. This is because we are inherently broken - we are sinful, we are born sinful. Children do not have to be taught to lie, steal, or hit others when they become angry; we do these things naturally. As we age, we don't have to be told to become tempted to sin, we are tempted because it is a part of our broken nature to do so.
2. Only those who repent and accept the forgiveness offered by Christ are changed - only they are not bound by the effects of their sinful choices; instead their choices' punishment falls on Christ, and his righteousness is imputed to them. It's an incredible gift offered in love by an incredibly Loving God. Those who reject this gift are punished by being allowed to do so - at a point, to the unrepentant, God says: "thy will be done". Before I was saved, I never realized how terrifying that truly is and will be (I was, instead, cavalier).
3. By your own earlier admission, your body is not wrong - your mind is. God did not screw up on you, he knit you together in your mothers' womb (Ps 139:13). Your mistaken impression that you are *really* a woman, and that - again, your own admission - therefore, since we cannot heal your mind, we must change your body is a part of your brokenness. That you seek to avoid healing your soul-brokenness via expensive and complicated plastic surgery and hormone injections doesn't mean you aren't broken - it simply suggests you are unrepentant. It provides strong evidence that you do not wish to go through the long, painful, agonizingly slow process of sanctification that ends with glorification and the healing of your soul, body, and mind.
3a. By itself, however, that evidence is not condemning, nor final. Plenty of Christians have been woefully wrong about a wide variety of topics, and they will continue to be woefully wrong about a wide variety of topics. If you are truly repentant, it could be that failing to see with and deal with this part of your brokenness is simply part of your ongoing struggle - at some point in the future, God may bring you to a point where you can begin to heal here, and that would be wonderful and a cause for celebration. It can happen. It has happened.
4. Unfortunately, you have another issue which strongly indicates that you are unrepentant, and do not wish to turn over your life to Christ when doing so would conflict with your desires: you claim to be a lesbian. Like artificially attempting to surgery-over your gender, homosexuality is a twisting of one of God's greatest gifts in a manner contrary to his will for our lives. Another way that homosexuality is similar to your continued search for a solve for your brokenness via cosmetic changes is that continued pursuit of it without acknowledgement of or attempt to leave that sin behind indicates lack of of repentant heart. Certainly it would conflict with claims that you are a repentant Christian. If you would so claim, if you truly are a woman, marry a man, or do not marry or engage in sexual activity at all. If you truly are a man, stay married to your wife, but do not disfigure the body God gave you to make it seem like that of a woman.
Saying this to someone is uncomfortable. The only sin that's still publicly recognized as such any more is that of "being judgmental". It's especially uncomfortable doing so to someone whom you like and respect, and with whom you have a relationship that you hope not to lose. My bet is that your friend didn't enjoy the conversation, but truly does wish good for you. It can be painful to love those whom you believe to be willfully Lost - the only thing I can compare it to is friends I have had who have committed suicide.
I should confess here that:
A. I avoid having conversations like this with my brother because of that exact fear (of driving them away, of losing them), a cowardice of which I am ashamed.
B. I am also a sexual sinner, who has failed more often than I have succeeded. Only continued love, mercy, and work from the Throne has caused what improvement I can see here in my brokenness.
Anyway, you deserved a respectful, but honest, response. I'm not going to take the easier way out and lie to you about it, I think the signs indicate that you are in real trouble.
