Feeling extremely down/lost/disorientated after holiday/holiday romance - normal?

Hi there, I'd appreciate some advice because I am seeing my doctor tomorrow (for something unrelated) and wondered whether I should mention this to him? I went on holiday for a couple of weeks to Cambodia, Vietnam and Laos and got back recently. I'd finished exams, was with my friends and it was a blast.. Since I got back, I've felt extremely depressed. I had the time of my life there and it was just so much fun. On the last few days, I met someone really special and then it was over because we had to go back on the flight. I remember the day after I got back, though, I felt like I was wading through treacle just walking around - I felt so low and lost and disorientated. I don't know how to explain it - it's like when I think of the holiday memories, my heart beats harder and I feel nostalgic. I feel anxious, like I left my heart there and I want to go back - like I came back too soon. I have a lot going on here now - starting my grad scheme soon - but I feel so unmotivated by it and unexcited. All I can think of is how I want to be back there :( I feel so hopeless, especially thinking of the person I met on holiday - like it was so unlucky to have had to go home and now I feel like there is no hope - like I am back to square one and it sucks so bad :( Should I talk to my doctor about this when I see him tomorrow? It's been going on for over a week now and it seems worse than simply post-holiday blues, doesn't it?
