It seems like I accidently give off the wrong impression. I tend to be very guarded, and won't talk about personal areas of my life. I am also very shy, but noone would ever look at me and see a shy girl. I just have a difficult time making small talk, and that makes me seem a little antisocial. 
 
This is the part that really causes problems in my life, I think. I am a paramedic, and I work with a lot of men and a few very tough women. I am not a tough person, socially speaking. I mean, I'm great at talking to patients, and I am a good medic, but personally I am VERY sensitive.  
 
I am also very young for what I do, at 25 years old. And alot of people say I'm very attractive. So what happens is that men are very friendly with me and are able to get through my shyness and make friends with me. On the other hand, some women look at me and think I'm a snob, or a flirt or too "girly" to be a paramedic, or whatever. I am nervous and shy around them and that makes me even quieter, so they think I don't like them or don't want to talk to them. 
 
Here's the background, and probably the basis for my insecurity: My mother was a drug addicted stripper and my father took off before I was born. My mother was so drunk and was always embarrassing me and my step dad was always walking around naked. Once at my Birthday party, my drunk mother pulled down her pants, squated and peed on the front lawn infront of all my friends. She then developed a worse and worse psychosis, and understandably, people were afraid of her. 
 
I stopped letting friends come over to meet her. But people found out about her anyway, as she liked to go out and party alot and she always caused some kind of scene. SO people would make fun of me when I was a kid. Peoplewould say "God Vanessa's mom is the biggest crack w****" and there was a guy I knew who used to say "Hey Vanessa, can you give head like your Mom?" I'm not complaining or giving a sob story, but I'm just trying to explain how I got so shy. 
 
SO I always felt like people were making fun of me or that they thought I was a sl*t like my mom. Anyway, I ended up getting a scholarship and putting myself through school and moving to a new city and working as a paramedic. Everyone here is great. They have great families and tons of friends and most of them come from lots of money. So I feel like SUCH and outcast. I am so embarrassed, that I just keep my mouth shut and don't get close to people.  
 
I had a good friend say "You know, you're probably one of the nicest, smartest people I know. I'm glad to be your friend, bu you're always pushing me away."  
 
I guess my question is: How can I get through my shyness and fear and the prejudice and show people that I'm really a good friend? I can't help being quiet, especially around really outspoken women who intimidate me. And I know I intimidate other people, though not on purpose. SHould I talk about my past or hide it? How do I get over the fear of being judged?
