A great effort, well done.
I did my physics degree part time and that took me 6 years so I know how you feel. When I finished my final exam I went and got two cans of Wild Turkey and cola and sat under a tree thinking 'my gosh, I can't believe it is over.'
I'm now onto the dissertation part of my MSc. That'll be over next May - should be studying now in fact. IIS is a great procrastination tool
Again, well done.
