Can I Just Stay in Bed Forever?

I saw Dr. K this morning and we talked about how I get overwhelmed so easily.  It basically comes down to the fact that I have no self confidence and am scared sh-tless to live my life.  I'm so afraid that I'm not going to be able to handle things (ex: a job, grad school, being a "normal" person, etc.).  I get anxious at the thought of becoming anxious.  It's so much safer to stay in bed under the covers than it is to go out and achieve your dreams.  Heck, who cares about achieving dreams, what about just being a self-sustaining, functional member of society.  I'm even scared to do that.  Since coming home from therapy this morning, I have been in bed all day, trying to block out the world and avoid thinking about anything.  It's days like these that I just want to go back to the eating disorder and escape my life...
