I'm 48, in my case it has gotten easier, the main reasons being that my sex drive has decreased and also reading redpill theory some years ago (specifically Rollo Tomassi, it's not PUA stuff) helped me to understand why I never had what women w/ant.
Understanding all of that pulled me out of my state of confusion about how things worked in life, so to speak, and that was a big relief for me. For some reason even if reality is depressing, understanding why it is that way helps me.
My copes are the usual, porn, videogames, but I also like art to an extent (comics and music mainly), and it's true that with time they kind of stop being as effective as before, but they're still nice.
I think in my case what helped me to endure my 20s and 30s is that I was still living with my parents so in a way I had a refuge from the world (even though I still had conflicts with my parents, being an only son failure and all of that), and back then my copes were very effective.
Between 38 and 47 I moved out of my parents house and shared rented flats with younger normies in a last-ditch effort to normalize, but it didn't work out, the social interactions caused me so much pain and anxiety that I ended up a bit mentally broken for a while, to the point that I had to abandon my line of work (software development) cause it was adding to the anxiety. I had suicidal thoughts for a while around this time and also a health crisis during which I almost deliberately didn't go to the hospital (I went at the last minute), so in a sense I almost tried to kill myself.
However during that time both my parents died and now I've moved back to the family house, so the good thing is that I can isolate myself and I only interact whenever I choose or when I need money. Also my expenses have reduced a lot since I'm not paying rent, I lucked out in this regard.
I think I'll probably reach 60 in this state, after that I don't really care.
