Feeling Lonely and Stuck—How Do I Cope?

I’m 18M and lived in Chandigarh since birth until 2018, when I moved out due to my dad’s job. So, while I spent my childhood here, my teenage years were elsewhere. I came back to Chandigarh in July this year but left soon after for college in August. Now that I’m back for the break, I can’t help but feel bored and isolated. The city feels dull and depressing, especially with the cold weather. I don’t have many friends here anymore, and it feels like there’s nothing to do. I’m struggling with this loneliness and don’t know how to make this place feel alive again. Any tips or advice to cope with this?
