Trial of Stinging Doubt & why won't it spawn???!!!

So I have been playing PoE for 2 years this month & still cannot get Stinging Doubt to spawn! What am I doing wrong & why is the RNG so damn sad for these trials? Only 3 will spawn 99% of the time, Truth, Fear & Pain. Once in a while, Rage which includes my own RAGE! 2 years and have yet to complete The Eternal Labyrinth! What gives?! Went through loads of Dream Trials, same 3 spawn over & over. GGG Come On Already! :(...

type /global 820 ask for trails
ask your friends put a stutus asking for that trail
ask multiple global channels for that trail

rng is rng.. use the help from other people as already suggested

PS: and do not demand it. just turn the global 820 channel on and wait until someone offers this trial. Then whisper to that player and ask him nicely if you can join:)

PPS: Ive been criticizing this for years, I think the chance should be biased towards missing ones, because it is the part of important character progression and should not be gated behind cruel rng that much. But devs have different opinion, perhaps thats the way how to force players into interaction with others

The RNG gating is silly, imo. At least now they've added it to Zana quests, so they're a bit more common.

Ty for tips but have been hangin' in G820 asking for help but seriously, 2 years and no Doubt spawn not even once? All my characters are gimped permanently unless GGG eases up on the trial RNG spawns.

That's the same one my level 88 guy in Delve needs for my final ascendancy. :(
