Loss of muscles

Hello, everyone!!! I need your help! I am a woman of 45 years old. Four years ago i started to train to lose my weight. everything was great. i was loosing weight gradually. but in winter 2008 my coach wrote me a special programme how to put on my muscles and i started doing it.i was training my muscles 3times a week, working for 2 hours. i was doing it for 2 months and then, suddenly, I realized that I have changed my body, my shapes radically. This training made me feel ugly, cause i stopped looking femine. And now I have large, mannish muscles and absolutelly different body structure. But, my legs and arms disturb me most of all. I want you to ask for a help!! Can you, please, write me a way out of this situation. How can I make my body the same as it was before gaining muscles??!!!! Is it possible to get rid of them. In which way? Thank you! I really hope yhat you will help me, cause you are my last hope!!! Note: I dont want to be like that,can you please advise me something to get my natural body as it was before training?
