I just want to say the same as everybody else. 2 Weeks ago I felt like I had a baby permenantly attached to my boob - I was feeding when she woke, after she burped, a little snack before going back to sleep - the whole time. She was fussing for hours during the evenings and my poor dd1 was getting cross.
Now I can see the light at the end of the tunnel, she's taking proper feeds, lasting 3 hours (or even longer if I let her) between feeds, still fussy in the evenings but much better.
Things change quickly at this age, set yourself a review date that seems managable, say 3 more weeks, keep going and see where you are then. I bet it'll be a whole different picture.
