Like pomegranate said you will still be you. You still are you now.
You have lost a tremendous amount and you are possibly already feeling quite different in your own body. Personally, I would take things from now at a rate that you feel comfortable in your head with. Discuss as much as you need to with your T. Your mind needs to be in sync with things too. Its not so much about our bodies but what is the driving force in our thoughts and emotions.
