Why do some people refer to themselves in third person view? Like they'll say, "Bob likes that" instead of, "I like that."

I would like to know why I feel like crying when I speak to figures of authority. It happens most often when there is a serious subject to discuss; however, it has happened when talking about good things, too. It has happened when talking to my parents, grandparents, boss, and teachers. The common factor is that I see them as figures of authority and we are discussing me. I can talk with these people about anything else, but if we are talking about me, I begin feeling the urge to cry. I bite my tongue to distract myself. It is very embarrassing and uncontrollable. The most recent outburst happened when I was asked to describe my strengths and what I need to improve. I could feel myself wanting to cry, but it was still controllable by biting my tongue and speaking in short sentences. However, the teacher began using a soothing tone, asking what I thought because I wasn't saying very much. I was no longer able to control myself and cried. How do I stop this from happening and why does it happen? I am otherwise a very outspoken person and have no issues with public speaking.

My friend has only been at college for two weeks, and she has already had sex with several guys. She is having safe sex, so it's not dangerous in that sense and she claims to be enjoying herself. However, it seems to me that such behavior is unhealthy and damaging to one's emotional state and reputation — but I'm not sure how to explain to her how I feel, or articulate what is wrong with her how she's acting. Do you think what she's doing is wrong, and if so, how should I confront her?

Recently I had my first one night stand. It happened with a guy at a club and it happened very fast without us getting to know each other too much first. The problem is, the next day I felt extremely sad and depressed. I felt like I've been used and felt cheap. I was also sad that he didn't ask me for my phone number even though I wasn't interested in him. I felt unattractive and worthless. Is it normal to feel this way? Do guys ever feel this way too? How can I get over this post-one-night-stand depression?
