Ice Queen

I know for a fact that to those who I don’t know very well or closely, I come off as a very cold and snobby person. However, I am not a cold hearted pompous being. I don’t like to talk much, nor do I like to share much personal information. I don’t make that many jokes, and I am very sarcastic. I won't be smiling much either. But that is only because I don’t know the other person very well. For those people who I do know and I’m quite comfortable with, I can become pretty difficult to keep quite and stop goofing off.
I really have no idea how I can become less 'cold and snobby' and more 'friendly.' I love to meet new people and learn about/from them nad become friends, but I'm just too...quiet and hesitant. Honestly, I wish I wasn't at times. I feel like I automatically put up a barrier between me and the other person, unintentioanlly of course. It just feels so...hindering....?

Also, in emotional situations, I feel quite uncomfortable. I feel very awkward, indeed. I have to feign caring and soothing actions. I mena, I understand the other person and all, but I just can't connect (unless it's some very close to me, such as a family member).
