Since I came back from my trip, I began to miss those days of traveling. I know I can't go back, but the more I miss it. Cause a feeling of a little anxiety

are you introverted? You should communicate and share more with others. You miss the days of traveling because it brings you freshness. People and things around you are strange, so you may be more open and have no worries. Do you care too much about other people's opinions, or are you under too much pressure to study? I also like traveling, and I will be a little reluctant to come back. I will share my travel experience with my friends. I will work hard and plan my next trip. You are confused now and have no direction in life. Talk to your good friends more, say what you want to say, don't suppress it, don't think alone. I don't know if I can enlighten you, but it's up to you.
