Re: so discouraged...
If it is lipase, and mine was - it wasn't a storage bag issue - you can scald it and freeze it. I would even scald todays, put it in the fridge, scald tomorrows, combine them when they are both cooled and then freeze. I probably wouldn't store it for more than a day or so, scalded.
I would also put the milk in the fridge and taste it every day for a few days to see how long your milk lasts. What I did with my milk was pump today for tomorrow, and then on the last day of the week, scald and freeze. I always used the oldest frozen milk on Mondays.
It does suck to have to lose your freezer stash, but better to find out now than when you are already working.
