I second Zelda09's suggestion of HeadSpace. Exercise has also helped me, especially yoga.

Do you have any close friends or family you could go visit for the weekend? I'm fairly introverted as well but I found it really helpful to go stay with a friend for a weekend just after BD who understood my need for alone time, but was also there for me when I needed someone to vent/cry/talk to.
