more of the same

I feel as though I am nothing but a let down, both to myself and others, physically, financially, and emotionally.  I feel paralyzed in my own body but don't have an 'egg tooth' to break through my shell.  I can do any work I am assigned, I can do anything, it seems, except land a decent and somewhat-enjoyable job.  I have so much potential and fell as tho I will never get a chance to show of what skills I do have,
