Is it so difficult to make good friends in life ?

I am 38M and live with family in Hyderabad. I was born and bought up in hyd and did my schooling and college in hyd...work wise moved out of hyd for a few years back in 2012 and moved back in 2016 when I started to work with my current company.

At various stages of life I have been able to make friends yet today I don't have any friends. School/College friends are busy with their lives and have moved to different cities/countries. At work, its all professional and tough to make friends for various reasons.

Off late I have started to think a lot on this aspect as sometimes I really miss having that bunch who you can chill with, share things, talk about life, who you can fall back upon, who can be said these are my family like friends.

Often when I see others in a group or even in reel life, I really start feeling lonely and wish if I was part of that group and had such friends.

I know its also about me and my personality (I'm a bit introvert, choosy and short tempered making me come across as not so easy) but I have always given my best to the people I choose to be friends with but never got that back in return.

After a certain age making good life long friends becomes very difficult but never thought it would be this tough and there would be a stage where I would feel this void of needing life long friends.

Not sure if anyone else around my age feels the same or may be have contrary thoughts ?
