And I am ashamed to admit that I have not been the example I should be of a good Orthodox convert who is wondrously happy and full of zeal. I believe I am going in the right direction, but this time in my life has been one of cleansing. Little by little, I am losing everything I once held dear. I hope God has a plan for all of this, but right now it's everything I can do not to hate Him for taking everything from me.
No need to feel bad - sounds like you are doing just what you need to be doing. Your friends will respect a well-intentioned struggle and effort rather than an "I've got it all under control" attitude. Every catechumen progresses at different speeds.
But you do concern me with the statement that everything you held dear is being taken away from you. Could you clarify what is being taken away that has upset you so much. The control of our sins and human weaknesses is one thing, but I hope, in your conversion to Orthodoxy you don't think you need to totally chuck your personhood, interests and beliefs all by the date of your chrismation (for example, you don't need to burn all your pre-orthodox books, cleanse your cd collection, and dress all in black
at least not yet). Conversion is a gradual process, and if you're struggling with hating God for the changes in your life, maybe you need to slow down. Convert zeal is a really powerful feeling, but it can be taken to an extreme. Just because your spiritual father is proposing chrismation by Pascha 2008, you don't have to be a saint or a monastic by that date. Give yourself something to work on for the next 20 or 30 years.
Talk honestly and openly with your priest about the struggles you're having. Besides talking to God and all his saints, your priest is one person you can and should feel the freedom to be frank with. Clairvoyance is a spiritual gift given to very few people, so chances are he can't read your mind.
My 2 cents for what it's worth but I hope you find a few words that benefit you.
