Loneliness problem in kota is unlike any other city due to specific reasons
This post is based on my experience of the past 7 years of living in kota during the adolescent phase of my life.
In my opinion this is an issue which manifests itself in a form which is very different from anywhere else.
I have tried to list all the probable factors and how they contribute to this issue.
Mindset of Temporariness - people come to kota for serious aim oriented study and do not consider forging inter human relationships worthwhile.
Niche nature of economy - the city's primary source of income is hyper specialized and it is obviously driven by the coaching industry. And because of this reason every business is targeted towards students. It severely lacks any avenue for social interaction apart from studying. This is not the case in any city where there is a diversity of social infrastructure.
Influence of dummy culture over normal teenagers of this age group - in kota individuals who do not follow this prepare for jee/neet (sometimes from a very early age) by pursuing anything apart from this are considered deviants instead of the other way around. (I speculate kota has the largest no of non attending aka dummy students in proportion than any other city in the WORLD). This dummy culture is so detrimental for the mind of a young individual. In these dummy classrooms there is an extreme skewed sex ratio since parents are comparatively more reluctant to send their girl child to kota for study. Apart from that there is a very tyrannical segregation of female students and male students where usually 1 out of 3/4 rows are seperate for girls or even different batches sometimes. Mixed sex classrooms during education is extremely important for secondary socialization seems to be lacking. (There is a new type of social stratification as well in kota which is very different from any other city, here people are UP and Bihar are not discriminated against because they take up jobs of the native people but because they are from those states. Even while they are the ones sustaining the economy of the city which would be dead otherwise.)
Marginal cultural modernization - we are stuck in between. The city is not modern enough to have a vibrant dating or clubbing culture but modern enough to not have traditional ties of kinship, childhood friends, cousins etc.
Absence of realisation - people think this problem only affects them, or they are the exception but in my observation both in physical interactions or by impersonating on reddit (not really proud of that). This problem seems to be unanimous.
Sorry for using ajeebo gareeb terms (Yo banne ke liye karna padta hai).
