Ive been where you are, even to the point that I believed Id rather be dead than have to live as male.
The enemy likes to lead us to be completely focused on the wrong things, even obsessed with them, in order to lead us to do what we know is wrong. They will even lead you to sorrow and grief if they can get you that far into it.
But, you dont have to follow what they press on you. I know the feelings youre dealing with, Ive been there and all that : p But the thing about feelings, they can change with the right mindset. Its entirely possible to change whats in your heart, if you let yourself make that first step.
Its pointless to become so worried about this form we take, we both know that it will age and die and rot. No matter how much work we put into it, it will be taken away. And when we reach those final days in this form, those days in the past that we lived "to their fullest" will be completely meaningless at that time. Memories are great and all sure, but how much do they help us in times of struggle?
Its entirely possible to change your focus, and to let go of things of the flesh. I and many other Christians have done it : p
You can totally talk with me if youd like someone to talk about this with.
