Have to disagree with Jeffs. Nothing (certainly not the first XC), comes close to that first solo for a sense of elation and achievement. The very first time you fly an aeroplane on your own - whatever follows, and it can be some amazing stuff, can never equal that.
Congratulations! I remember mine back in 1978 after 10 hours dual was quite unexpected. Tom Dugdale walked away from the clattering old C150 having folded his straps on seat, saying in answer to my astonishment "you're better than you think you are. Enjoy it".
Metaphorically, I didn't come down to earth for days! 35 years later it's still a major highlight of my flying life.
