If you want to get out of the hobby, just put up a Craigslist ad and sell your tank cheaply, someone will buy it from you and be happy they got a deal. Members on here would be glad to get your fish, I'm sure.
If something went wrong and you got discouraged I can understand, but if you just lost interest then...probably best to cut your losses. No one is too busy to feed their fish, it doesn't take any time at all - "too busy" is no excuse. If you don't want to see the tank and/or fish anymore, then pass it along to someone who does. The tank is making you feel bad, your fish feel bad for being neglected - sounds to me like it's just time to break the cycle.
