Aside from the obvious advice to keep your expenses as low as possible, I think you might consider a change in attitude. You are playing a game with a positive expected value, but the rules of the game are such that payoffs are very large and very rare (if you've read The Black Swan, think Extremistan). Unfortunately, the game of "paying my rent check" and "eating on a daily basis" follows a different set of rules. You've been allowed the privilege of taking a risk due to your savings; once they are gone you will be playing a different game. When that time comes you may just decide that "some business guy's lame vision" is a decent alternative to being hungry on the streets coding Haskell. The choice is up to you.
Also, stop feeling scared and terrified (your words). These emotions are not helping you in any way.
