You definitely need a new T. I can't believe they said that to you. Utter crap!

For what its worth, nothing you have said, has made me think you have done anything wrong at all. I really can't see anything in what you have said, that makes me think you have any reason to be ashamed.

This line makes me sad. You should not be forcing yourself to go against your own sexuality. If you are aroused by guys and girls then you are bi. Theres nothing wrong with that, but there is something wrong with forcing yourself to go against your own natural desires.
