Frustrated seeing all my friends having fun

Okay so I graduated from an IIT just last year with quite a low paying job (3lpa). Didn't really like the job and always had a keen interest in UPSC, so quit the job after few months and started preparing for my first attempt from home.Now even though the prep is going fine, I sometimes check my insta story and see all my placed friends having fun together, going to concerts( Dua Lipa yesterday) and I kinda feel left out since we used to have all the fun together in college.I feel frustrated and start questioning myself did I really take the right decision. Can anyone tell me is this feeling normal and what should I tell myself to feel better. I also don't have any friends here so can't really talk to anyone.
