I had to giggle at your post. Not because you got a flat on a new tire, or not because you struggled (really sorry about that)- but because that was me changing my first rear flat. It took me forever and when I was done cursing and fighting the new tire to get the bead back on- I had to sit back and laugh at the whole situation. Difference was I was on the road and had to do it far from home. I must've been a sight (that's why I laughed at myself).
I giggle because I can just picture what your struggle looked like- and how frustrating something so seemingly simple can be (and then the guys at the LBS take it off, change it and put it back on in less than 2 min. ).

We're all VERY proud of you for changing it and getting it done. You should be proud of yourself, too! Empowering, ain't it?
