Hi RavenHairedPrincess - Yes, I can relate to you. I had a terrible time trying to BF (EMCS, small baby, wouldn't latch, undiagnosed tongue tie, getting stuck on the BF/top up/express roundabout) and it made me miserable, but I was devastated about it all and didn't want to stop. I also asked two GPs about domperidone and didn't get it. A BFing counsellor, when I asked should I give up, said that only I could decide that but it may make the decision easier if I had thought that I tried all avenues (so I wouldn't keep thinking "What if I had tried that?").
I decided to cut back on the BFing and only feed twice a day and give bottles the rest of the time (no more expressing). Yes, I felt awful and guilty for some time that we hadn't managed to BF properly but at the same time I was also happier as I was far less stressed, my baby was fed and I had more time to enjoy her. She's almost 6 months now and we're still managing our mini BFs (I call them that because they are in addition to her bottles, they don't replace them). I was speaking to a counsellor about this recently and when I said "But I'm not really BFing" she told me to stop thinking in terms of mls of milk and about everything else that it offers us both.
I guess my point is that you don't have to give up completely and can mix feed, as you suggested you might do, but it's really up to you. Only you know your limits and what's right for you both. You may also be interested in reading the 'Support for those who FF' feed - I'll bump it for you.
But above all, don't feel guilty! BFing isn't always easy - you should be proud that you've given her 10 weeks of breast milk, that's a Good Thing.
I wish you luck in whatever you decide :)
