Its been a 24cent (15.5%) fall from Fridays close. Given the price has fallen consistently from the recent high of 1.80 (27% fall), its fair to assume some of the policy announcement was already factored into the share price prior to the Sunday announcement. This is all on the back of a proposal that has yet to get legislative approval and only has a 20% affect on the NPV according to the AFR. You are right that Abbot will eat this for breakfast. Any further fall would be well into overshoot territory imo.
Re your waiting for the day to get out at breakeven - its hard to do, but if you can emotionally separate the past from the present you will make a better investment decision when the time comes. I would hate to see you sell at breakeven, only to see it go much higher. It will only double your angst. Sell by all means (even if below breakeven), but with a clear head and with a little left on the table for the buyer.
Good luck in whatever way you handle it.
Cheers Bleasby
