Yeah, I also underestimated the effects of feeling support. I've been feeling infinitely more secure since my mother promised to help me shop for clothes, and the laser people told me I looked more like a girl than a guy. Before I was terrorized about going full time this summer/autumn, all alone, and super insecure about my lack of breasts or a female-shaped body. Now I'm still scared, but I'm facing the scary obstacles with courage. Well, if not courage, at least not terror.
The simple fact of being alone makes everything infinitely scarier.
