@DharmaGirl I'm only able to answer from my perspective. Friends come and go, friendships happen quite differently with different people, and with all of these....I do not push friendships....I let them happen.
Acquaintances-low level friends-you don't tell personal stuff to because either the relationship is a casual one, and you share your time doing an activity, they are a neighbor who just watches your home when you go away......I have a number of people here. These people may or may not gossip-I don't care. Co-workers usually fall in this category....I may have known these people a short time or a long time, but I'm satisfied with the distance in the relationship.
Good friends-I have a couple of people I'd name good friends, but I still keep my anxiety, serious health issues, and gossip worthy stuff to myself....but I do share more with them than acquaintances. Trust is being built....but they are not best friend quality....that takes a really long time doing. May or may not communicate regularly-have known for years.
Best friend-I have one, known her 16 years, she keeps confidences confidential, and doesn't gossip about me, communicates regularly (weekly) and will ask me for help or I'd offer right out. Weve traveled together, been at each other's house for the holidays, know each other's family. I'd leave her in charge of my funeral and whatever estate I have left because I trust her to make my life decisions (if I were dying). She has proven over a long time how trustworthy she is, and shows give and take in the relationship, without ever any malice or intentional/unintentional hurt.
Then there is sexual partner....lover....yeah, none of those came from long-term or best friends relationships ...they started out as number acquaintances (My parents left out the lesson on best friends first-hit the sack after you develop a friendship -that takes more than a month or two....hormones ruled in those days).
This is just how I see friendships in my life. I am grateful for having these people in my life....
Similarly, regarding changing the tone of the conversation, I was diagnosed with cancer recently. Somehow I have it catorgorized and I'm going on, you know, like nothing's going on.
I've told some people though and nobody takes it well. Me included, because I don't want to talk about it. People look scared when you say it. Nobody wants to know about the big c. Then I have to explain the whole thing.
I'm like the person in the movie who knows the monsters are real. It's a burden sometimes because I like to talk. It is soothing for me. It took me 4 years to get most of it out in therapy.
I write a lot because it is lonely sometimes. You want to feel a connection with someone else. I think most people who write a lot are lonely. Once a week with the therapist seems not enough.
There are not lots of places to go with it. I'm getting used to it.
I hope that you have a positive outcome on your health. Sending you some positive thoughts and energy for that. But about the writing, I'm quite verbal, too....sometimes too much so and writing these past few years, a positive outlet.... Am I lonely...sometimes more than others.......well, a lot less now than I was, as I'm allowing myself to connect with others and slowly, build new relationships.
Good luck.
