Friend vs Loneliness

Nowadays, it is difficult to maintain friendships (old friends) as many are pursuing dreams and for that one has to shift for other countries/state and the rest busy with there jobs and family business.

New friends are difficult to make where people already have there groups of bunch of friends where they don’t want anyone else to join (old friends groups) & also as the smaller groups are easy to manage and for execution of any plans.

While growing up due to change in habits (smoking, drinking, etc) of our friends we did lose few.. and now they don’t call me up for any plans!

So, basically i am left alone with nobody by my side apart from cousins of same age (more or less)!

Most of the time, I spend my day working on my business.. or at times, working out or reading books.. But at times, i am left alone with my own thoughts and that feeling at times is exhausting and frustrating and sometimes this loneliness becomes toxic!

Can anyone help.. how can we make friends in midst of all this?
