You asked how to solve the loneliness epidemic. I provided citations and recommendations. Are you asking me how to be the person you need to be to make bids for friendship and connectivity to establish community? And where to find people you can have an opportunity to make connections with? I can do that too.
> I'm trying to reach those people who feel the way I feel have no way of connecting with anyone, or at least feel that they don't. Do you have any new ideas of how to achieve this?
Go out and find people looking for other people. Volunteer and find events and gatherings scoped to building connections between people. Third spaces are in decline [1] [2], or in some places, non existent. This will be work. It will not be easy. You will need to work on managing the feelings of rejection and shallow people not genuinely interested in you or building a friendship (boundaries are important in this regard; have them, communicate them, and enforce them). Success is not assured. But your only choices are to try or not.
From your comment:
> I also had it hammered into me as a kid that nobody wants me around, nobody could ever love me, I'm a failure, a burden, a creep, a weirdo, and nothing but a bothersome nuisance that nobody would ever want to spend 30 seconds alone with. I'm trying to reject these thoughts, but it's difficult when you have nobody to talk to. It's like pulling yourself up by your bootstraps. I wonder how many people have the same issue. I've made a few friends in person, but I rarely get to see them.
In regards to this you commented, I highly recommend therapy if you can access it. It will help. This is an unnecessary burden to be carrying through adult life, and a professional might help unburden you of these feelings. The healthier you are emotionally, the easier it will be to create and maintain interpersonal relationships.
Does all of this suck? Oh yes, certainly. But we play the hand we're dealt to the best of our ability. Good luck, in as genuine terms as I can communicate in text. If you feel like I can provide more value with more questions you might have, I will do my best to help.

(tangentially, I recommend replacing "idiot who doesn't understand anything" with something more like "I am early in my journey to understand, but I look forward to the experience"; love yourself first, we are all learning and sharing for the portion of the timeline we share, and it is okay to not know if we continue to want and try to learn)

I'm not the GP, but I have the same experience to them. I have been in therapy and on psychotropic medication my entire adult life, that's 2.5 decades. I'd love to know when exactly the "unburdening of these feelings" happens.
I agree you (OP) must work on developing a positive view of yourself. Maybe therapy. Don't overlook clergy even if you're not religious. Religion is as much about fellowship and how to live a fulfilling life as it is about worship. Some churches (e.g. unitarian) are quite inclusive and are much more spiritual than dogmatic.
But you will find it much harder to attract friendships if you come across as needy or wanting to unburden a lifetime of problems on your new prospective friend. Not to say a longtime friend can't eventually handle some of this, but it's not a good way to start off.
I would say avoid groups that are focused on personal success or networking. These tend to be full of people who are looking for an angle or benefit for themselves, not people genuinely trying to develop friendships and connections with a community.
