"But right now I just feel like wanting to turn myself off from interacting with folks until it feels like things change for the better"

You aren't alone in this. It may sound weird, but the changing of the seasons can be to blame for this and there's many papers on it. It's called Seasonal Affective Disorder.

Just mentioning it in case it helps.

You take care of yourself.

Perhaps you're just not as conversant as you could be. Generally, if you're an interesting and enjoyable person to talk to, people will want to talk to you more. Conversely, if you don't chat people up regularly and don't offer much conversation beyond simple greetings and courtesy, people won't talk as much with you. All relationships, ultimately, are transactional. Make sure what you're putting into one is the same as what you're getting out of it (or hoping to get out of it)

Personally, I put a lot of effort into my connections with people, brainstorming cool concepts and recommending things I know they might be interested in. Hence, I don't waste my time with people who don't do the same for me. I think many people can say the same.

true true completely agree there

There are times when I reach out to people and nothing comes of it or they take a long time to respond. Usually I don't think anything of it; nowadays people are so busy and caught up in all the events in their lives that it can be hard to manage the time. Especially if your neurodivergent; I know because I've been on the opposite end and sometimes it takes me a lot of effort to just organise myself to eat at the correct time let alone manage all my messages. I know it can be rough though, especially if you're feeling lonely or isolated.
