Hey michelle, I have a couple things that you can do...
I believe shyness comes from being very involved with what others think of ourselves, negative thoughts about ourselves, and being generally self concious about ourselves in social interactions.
One thing is to flip your focus. Instead of focusing on yourself and the things you do awkwardly in social situations, focus on those who you are interacting with. Become curious about others in your life and the things going on in their life. The more you feel an urge to find out about others the less scary it feels. We as shy people, feel a type of loneliness and with that a resentment that people do not know or understand us. Give what you want to receive. If you wish others would know you better, work on understanding those you care about in your life. You can never live their lives but you can offer to share in it.
It is very freeing to switch focus onto others because you will not feel that scrutiny from yourself, ie. thoughts of I'm not good enough for them, why is everyone else comfortable at this party, etc. And you will get interested in others providing them the best gift of all.
Another, thing I would suggest for you michelle is if you evaluate what you want and create acheivable goals to work towards. Once this starts, you have control of your own life and a greater happiness and strength in yourself. Goal-making is a typical tool of therapists and is used very effectively to help overcome anything including shyness. If you feel that you would be helped with a therapist then go on your Health Insurances website and find therapsts in your area who can help.
I work on both goal-making and constantly making an effort to get interested in other people and have made great strides in fighting shyness in my life.
Hope this info helps!!
Good luck!
