Re: Is it time to throw in the towel?
I'm sorry you've had such a hard time with BFing! It sounds like you had a really, really rough start, and it's AWESOME that you've hung in there for 7.5 months.
Whether or not it's reasonable to stop BF now is something which only you can judge. What will you feel if you stop now? Will you always kick yourself for not continuing, or will you be at peace with the decision? I almost gave up when my kid was only a few weeks old, and realizing that I would have felt guilty forever kept me going. (Not that I'm implying that you should feel guilty- that's just how I felt about it.)
I think it's possible to get a full supply going- your baby will actually nurse (!!!), it sounds like you may have the right pump (I'm guessing a Medela PISA, right?), you still have milk... But only you can know if it's worth the effort. I would see a lactation consultant and see if she can give you a personalized program to get your supply going, and see if that's a program you can live with.
If you don't want to go forward with relactation, how about ditching the pump, nursing your baby as much as you can, and supplementing as much as you need to? BFing doesn't have to be all or nothing: Partial Weaning and Combination Feeding.
Regarding the lopsidedness, well, that's actually quite normal for many moms. It should disappear once you wean. If you want to deal with it now, the best thing to do is to pump the underproducing breast much more frequently than the one that's producing more. The additional stimulation will increase supply on that side, and increase size as well.
