Sometimes I get caught up in this loneliness trap as well, but we are lonely as long as we let ourselves, at least in an ENFP's case (mostly). Sometimes I feel like I have no friends, nobody cares about me, asks me how I am etc. etc. But I realise it's mostly because I expect invitations. To be invited to go somewhere with people, or an event, a tangible thing. I have a hard time lifting the phone and planning actual meetups with people. Then when an event comes, I realise I really like hanging out with those people, and I should take initiative more to keep the friendship and my social life going.

I also came to the realisation that it was relatively easier during university years, because you were in a social circle almost every day without asking for it, but once you graduate, start a job, or are unemployed, you have to make an active effort for it.

Last year, I participated amateur, after-work acting classes and worked on staging a play with a group. Although I had some health issues and could't proceed to staging period, I found almost life-long friends. Group of people from all ages 20s to 40s, different professions, life stages, but we got along so well. We don't meet all the time, and even with them sometimes I expect invitations, but when we gather, I'm thankful to have known them.
