You are going through a rough patch mate, and I hear that. It's hard to offer anything that will help that hasn't been already said. I'm sorry you feel so disconnected and hope you find a way out of that sooner than later.
Funny I had a DM in the garden withy bro in law yesterday. He tends to do that, just chat about deep shit. We are kinda the same age, I guess an age when you think about your mortality in the face of it all, life's purpose and all that. How to live a meaningful life knowing you are going to die any time, get sick, lose people, even facing the death of humanity as we face the last seconds to midnight. Buddhists of many kinds meditate on illness and death as practice, as if life is a preparation to die. Where do we find comfort in that? Yes, to connect, but sometimes it's not necessary connecting to fellow humans (although that's GOOD), it's connecting to the entire universe. We are all dust, stardust to be hippy about it, from chickens to leaves to ants to clouds to rivers to your great uncle Peter. And if that's not connected I don't know what is. This idea helped me enormously when I was on my knees, metaphorically, when Dad was dying.
We find our ways through. Sometime the journey there sucks balls..
And do keep your dark humour. It's a good brain function thing I reckon. Helps see the cosmic joke of it all.
