However, the fact that you blindly sent this to me without any evident research into who I am and what I do suggests that time spent on assisting you would be wasted. Do your homework.

I would suggest that you focus on just getting a new job. Also it is generally useless to appeal to a potential employer's sympathies.

I've attached my resume.
