I went a couple of times years ago when it was just starting to turn into what you describe. Had a great time, but it quickly priced me out. Now, it sounds like an influencer-laden hellscape. The addition of premium plug and play sites was the nail in the coffin. That said, a lot of the old time Burners are fucking amazing, creative, resourceful, and helpful people.
I cut off contact with my narcissist father and stepmother about 8 or 9 years ago. I had previously cut off contact for a year or two at a time, but would feel guilty and reconnect and nothing changed. This time it’s permanent.
Since then, my mental and emotional health has vastly improved. I have accomplished more in these years than in all the previous ones. I now have a great writing gig and life isn’t perfect, but it’s better now than ever before. If I ever did speak to them, the only thing I’d say is, “I couldn’t have done it with you.”
