I hope you enjoyed that coffee. You've certainly earnt it. I could never give up coffee
Have you tried calling the ABA help line and talking to a counselor? They can help you to give it one last try before you give up forever and if you're just not up for one last try they can give you the right advice to make sure that the transition off the breast is smooth and you don't end up with dreadful engorgement.
I hope you don't mind me saying, that reading your story, it seems that you have done everything you can but you have been let down by lack of support.
