Thank you for your suggestions! It really helps me a lot!! O(∩_∩)O~

Wandering around ( I'll be very grateful for your correction! Thank you!! ) This is how I might put it. Hope you dont mind my comments/suggestions. It's a lovely piece and very evocative. Hope this helps. Simon Here comes the winter holiday. The time passed by so fast, I didn't even realize it (or.. the time had passed by faster than I realised). My friends and classmates all left this city for home. But I chose to stay. I spent days wandering aimlessly round the city. The feeling was amazing. In the past, whenever I went out for affairs or a trip, I would make a plan, no matter what. This time, instead of calculating and worrying, I shed the burden of my mind (or I freed my mind) and just kept walking until I grew tired. I stopped and walked at my own will. Thankfully, I found somewhere interesting to visit during this aimless walk (you use aimless twice - you could try a new word - perhaps one that that summarises how you felt after the walk and links to last sentence, e.g. uplifting, soulful, restorative- just a suggestion - you could even add unexpectedly into the mix, e.g. unexpectedly uplifting) . I found it a helpful way to heal anxiety or depression.
