@Chupachups. Welcome to the forum and thread. Honestly, Didn't therapist gave you some advice. In my opinion, To overcome a shyness is not hard, But to overcome a childhood trauma is other thing. I think you should, as others said, try to pratice. But you could try to talk to male therapist if you never done. He probably mitigate awkwardness in yourself better than female one.
I thought I would suggest you to google some boy's face and try to pratice with it. But it's probably have some side-effect which I thinks it would make you worse.
@Neotoros No! The most beautiful girl isn't your love. I mean, by what right do you have to judge a girl as "most beautiful" while being simply 1 (or a few) out of 7 billions of living human. At least show some respect to my own.
Just kidding, I understand love (A kind of love, actually). She might not be the most beautiful but for some reason she already taken your heart to other side of the world (if assume that she isn't in Africa). I suggest you to keep talking with her, Follow your heart. Because it's make any schoolboy like us feels like we have taken dose of pure ecstacy. Maybe indirectly tell her that you like her (because I can easily imagine how awkward it is to being near a "friend" who loving you and try to show it now and then) Someone, probably Walrusfella, told me that don't try to make platonic relationship with her because it will not end well.
Oh? Her name is Mattia. Right? You aren't not quite good about "privacy reasons", especially when I consider myself to be a potent stalker via internet.
Mini-Update : Moral of Yesterday - One of the best way to keep yourself from playing facebook for (yet another) admission test in first weeks of 2013 is tell your crush to do so.
Moral of Today : Some girl (like my crush) simply feels empty with "Singled" status. She might switch back to "In Relationship" despite it's ended in real life.
