Thom,first of all I would like to say I feel for your predicament. Being unemployed is no fun.
Using a computer all day without purpose leads one to go stir crazy. You lose your focus and ability to be a mentch.
One thing going to yeshiva does for you is give you both a schedule and purpose in waking up. They have morning kollels designed for people in your situation. Alternatively, you can arrange for a chavrusa in many yeshivas. I wish you much bracha and hatzlacha.
