It’s completely normal to feel lonely at first. I Left my hometown and moved to Gurgaon 4 years ago and struggled for the first couple of months without old friends.
Over time, I bonded really well with my colleagues, and also took solo trips, where I met a lot of amazing people (and trust me I’m not very extroverted!).
Focus on staying busy with hobbies, join some sports club (may be a Fitso membership?). Blr also hosts a lot of events and meet ups on a regular basis. Lastly try reconnecting with old friends and family over calls. That eases the feeling of loneliness a bit.
You'll adjust and find your group eventually. Don’t worry. :)
