Is she losing interest, or am I overthinking this?

So I have been seeing my girlfriend of 9 months and everything has been great so far. We live in different cities and we usually get to see one another a couple of times a week.

Thing is, she has become a little bit distant lately and things are not the same as they were in the beginning. The intimacy and conversations have become very dull when we are apart and she has put this down to her mood and lifestyle when I asked.

We were meant to meet up tomorrow and she cancelled the plans just now saying she will be too tired and perhaps we could wait until the weekend. I said that was ok and although I was moody as I had to reschedule my day tomorrow I agreed. What bothers me the most is that in the beginning we couldn't wait to see one another and now I feel like I am being taken for granted? Or am I just overthinking all of this?
