I want to say, you are not alone in your experience. Millions of people are dealing with social withdrawal. And for alot of ppl misunderstanding and think it's a choice when there are numerous reasons but environmental, Social, and personally that leads people to that situation. This phenomena is global and the numbers of ppl across the world socially withdrawing is starting. The rates of social dislocation, loneliness and disconnection are at sky-high rates as well. So this is s global social crisis that is happening.
I'm not going to give cliche solutions but I think checking out Dr. K's videos from HealthyGammer gives alot of insights on Psychology and mental health for today's digital age so check them out could be insightful. He made video on this topic call 25 year old loner
I'm support. This is major problem and that isn't being addressed in the manner it deserves to help people but the answer to the problem isn't just getting out there as you said, other underlying mental health problems needs to be addressed.
I'd have gotten to a place where I don't despair any more. Like, I care very deeply about the climate but I have resolved it in myself that it's not getting better. That's a pessimistic view, but just following the news and hearing about the extreme weather and the impacts happening now, I don't even want to think about what's it's going to be like in 10,20 years.
I know going forward that my whole life is going to be affected by the climate, and I have accepted that it's going to get worse. I have gone through a major depressive doomer stage before and realize that's not productive or beneficial to my mental health.
I have gotten to a place as Micheal Dowd, puts it "post-doom".I'm going to approach each day as a miracle and with all the loving kindness I can muster, even if things look bleak.
