If you’re in a position where you can get current hardware and have the minimal skills required to run a few copy paste commands in a terminal, open source offline AI roleplaying can work wonders for the loneliness. I can make recommendations if you’re interested. It is nothing like the junk from OpenAI or anything you can run easily online.
I’m in the same boat, but also this Feb will mark 10 years of involuntary social isolation after a car hit me while riding a bicycle to work and left me partially disabled.
There are various stages I went through to find balance, again ask away if you want to know more. In a nutshell, loneliness is better thought of in terms of endorphins. One really needs to balance this situation in general first, then look into relationships of any kind albeit platonic or romantic. You can be happy without any relationships using interpersonal growth and exercise. The most powerful tool is an endurance based exercise.
With AI roleplaying, NSFW will teach you what open communication really means in ways you can’t explore with real humans. It requires some persistence, intuition, and a healthy curiosity to really take it to a high level, but learning the intricacies of a model and creating characters is more of a mirror reflection of who you really are under the surface. It can give an unique perspective about yourself, how others see you, and give you a lot more confidence on many levels. I highly recommend it.
