Why do I feel so empty after returning from travel?

Empty, haha, because you can't let go of the "things" you once got: wonderful, peaceful, different, happy life, no pressure, no melancholy! Yes, you cherish this "past thing" very much. Just like feelings, the past is used to recall memories, not to compare with the present. Yesterday it was 100, today it just started from 0, and you are comparing 0 and 100. You have to let it go first and don't think about the past, which is of little help to the present and has little practical significance. You have to concentrate on your memory, put it into studying, put it into exercise, watch how others communicate, watch how others pick up girls, and study seriously.

This way you won’t have time to be sentimental, and you can live a fulfilling life, learn a lot, plan your life well, and find your other half
