Jasper, I want to congratulate you on sticking it out this far. It hasn't been easy for you, and you should feel great about what you have worked through.
How well I remember that time! I was three weeks into it - and decided to give up. I was exhausted, and absolutely nothing seemed easier to me than the thought of warming up a bottle and handing it to dp, and letting him deal with it. But instead, I opened a pamphlet the hospital had given me, and there it was, in black and white - it said that the three week mark is when most mothers, who are not feeling good about b/f, give up. I wish I had the booklet in front of me so I could quote to you why, etc., but just reading that made me determined to not be part of that statistic, and convinced me that it would become better so I decided to perservere for another week. And then another, and am just now stopping(dd was 11 mos. yesterday).
I became quite good at feeding her lying down - when I think of all the midnight feeds that I just snuggled her in between the two of us, rather than having to get out of bed, go to kitchen and make a bottle - i'm so happy I stayed with it. And when I did go back to work at 4.5 mos., I knew this was definitely something nobody else could give her.
And the time passes so quickly! It is hard for me to remember that dd had a time that all she had was breast milk - and it seemed as though everything in my life was about b/f - if I wasn't feeding her, I was getting ready to, or had just finished! And the pain - in my nipples, in my back, etc. No time to feed myself - all hot meals got eaten tepid at best. And in a snap of the fingers, that singularity of focus is over - the feedings become more spread out, and before you know it you are handing the jasperling a banana to chomp on...
So best of luck - and as I was often reminded, any bit of breastfeeding is better than none. That kept me going for a long time, as I just kept pushing out stopping b/f one week/month at a time, rather than committing to a long time frame.
