(((hugs))) Of course I know just how you feel! Once you find someone in your life who REALLY cares and tries hard to understand and usually does, it plugs a very big hole in your heart! The thought of now losing such a wonderful "find" is overwhelming!
Don't worry about losing T. Don't worry about your love for your T. Some of this is necessary for a good therapeutic relationship. It will tone down some with time, imo. Right now, it will help you to not take advantage of the T's good efforts to help you, in that you will be considerate of T's personal time and not call and call and call needing attention. (I hope it doesn't keep you from calling in a crisis though.)
When you're able, discuss this with the T. The discussion is part of the process of healing, and is very therapeutic too.
