Just wanted to add...
that you should check out La Leche League's website,
www.lalecheleague.org and see if there is a meeting near you. If not, it sounds like there is a definite need, and you sound like a great candidate to start one up in your area.
The website also has lots of useful information. You might also like the book The Womanly Art of Breastfeeding. It has a ton of information in it. If your doctor is willing, have him read it too.
And I just wanted to second (3rd or 4th) that you really are doing great, it is quite an achievement to do what you know is right with breastfeeding when you don't have a lot of real life support!!! You go Mama!
