No, it is definitely still exciting! You are so close, but don't let that excitement get in the way of logic. I read a bunch of opinions on whether it's a good idea to accepted an unfunded Ph.D. and most people said definite no and that the majority of unfunded Ph.D. students never get funding after the fact and actually drop out due to the cost. I would just take another year and try again! I have been hearing great success stories of taking a year and fixing parts of their application that were weak and getting accepted into every program they apply to! But don't give up hope it sounds like they are working to get you funding!
