I feel very depressed when I come back from my trip and want to cry.

Traveling is a pleasant and relaxing activity, but sometimes, even if you have a good time during your trip, you may have some mood swings. The following are some suggestions, hoping to help you ease the emotional loss after your trip:

1. Give yourself some time: Don't try to get rid of this emotion at once, give yourself some time to adapt to the environment at home and slowly adjust your emotions.

2. Remembering good experiences: Remembering good moments in the journey, sharing them with friends or family, or writing them down to make these good memories more profound.

3. Do some relaxing activities: After going home, do some relaxing activities, such as taking a hot bath, watching a movie, reading a book, taking a walk, etc.

4. Sleep: Adequate sleep helps to relieve travel fatigue and mood swings, and ensures adequate rest of body and mind.

5. Seek support: If you feel depressed, consider seeking support from friends, family members or professional psychologists. They can give you some advice and support.

Most importantly, don't be too hard on yourself and give yourself some time to adapt and recover. Travel is a pleasant and relaxing activity, but sometimes, even the best travel will leave some regrets and sense of loss. It is important to learn to accept these emotions and try to find appropriate ways to deal with them.
