Stefka, I saw your post on the other thread about being judged - if you do decide you can't go on BF, I would completely support your decision and indeed you: I would never judge you for making that decision and I hope most other MNers would be the same.
I'm trying to encourage you to carry on only because if and when it does get better it can be an amazingly positive experience. But if you can't go on, you can be assured that your baby has had the very best start from you, with all those antibodies and stuff, and you will have done you absolute utmost in very VERY difficult circumstances.
I have been exactly where you were. With DS1 and 2 it took 8 weeks and then 12 weeks -that was the thrush - before it stopped hurting and it was REALLY excruciating. I had the bottles and the formula at home with both but managed not to use them.
It must be exhausting and excruciating for you. It must also be very miserable feeling you're making no progress - but you have been feeding your baby yourself all that time, in spite of the pain. What a star that makes you.
If you're able to get to that specialist clinic, that might help.
Even if you give bottles, I believe there are people on this list who can help you restart breastfeeding later if you want to go back once your nipples have healed (though I have no idea how easy/difficult that could be).
But if you can't carry on, when you have tried so hard and taken all the advice and treatment you've had to face, then you've done your absolute best. I hope you do find a way through and give it one more day at a time but if not, best wishes with your decisions.
