Hopefully you still have your snake and haven't given up on herping just yet...

Many people have given you great advice so far so I will keep this to the most important thing.... YOU'VE GOT TO STOP HANDLING THE SNAKE. It sounds like you think you HAVE to handle it so that it gets used to you and stops striking. At the moment, it's quite the opposite. With a snake like yours who is very stressed out and aggressive, all you should be doing is leaving it completely alone and changing its water. Put some more junk in the tank so it's not so open. And in a week or two of not messing with him, then trying feeding. Honestly, just leave it alone for a while.
