I think I understand where you are coming from as someone who currently prefers short duration psychedelic experiences, especially one that comes with DMT.
It's short, and it relieves you of needing to have any control because of the complete loss of ego associated with larger doses.
When I was younger and life was devoid of any serious life altering responsibilities like a flow of income and taking care of your health, taking psychedelics always came easy to me. I relished in 4g mushroom trips on a weekly basis and never had any issues albeit maybe some uncomfortable social interactions or generalized anxiety on a solo trip.
But now that I'm older and my brain is filled with anxiety ridden tasks like planning ahead of my future, excelling at my career, and being conscious about diet and exercise etc, I've found it difficult to let go during a psychedelic trip for a prolonged duration.
It's completely normal to feel unsure about your ability to handle a powerful hallucinogenic experience. Good news is you have options.
1) If you are hesitant to jump into the psychedelic abyss, maybe you shouldn't. Having doubts is a tell tale sign that you may not be ready for an introspective experience, especially if you feel like you are in a dark and unstable place in your life.
2) I encourage you to heavily research what it's like to take psilocybin. Read books like Food of the Gods by Terence McKenna. Read the vast amounts of trip reports posted here, on Erowid, and TheShroomery. Get a sense of the mushroom and make friends with it before taking it out on a date.
3) Start with very low doses and work your way up, allowing your body and mind to get to know the substance a little at a time. Take it out for a cup of coffee before asking it out to dinner or for a sleepover. (The analogy here obviously being a real date lol)
If you feel like you can only consume a substance that puts you in autopilot, psychedelics might not be the right medicine for you.
For me... I like to make sure my ducks are in row with my life before undertaking a psychedelic journey... as loving someone else can be difficult before first loving yourself. I know it's a cliche, but it most certainly seems to be the case for entheogenic plants that demand respect before engaging with.
TL;DR : Do your research, learn, start small, take your time, get your life in order. These substances are not "cure alls" as a lot of people like to preach. Yes, they can be temporary bandaids, but they should be treated as medicines for life's many ailments.
That's just my 2 cents from someone who is currently attempting to muster the courage to start trying mushrooms again. I will be trying Mescaline soon, which I hear is a bit easier on the psyche as it is a phenethylamine like MDMA and not a tryptamine like LSD or psilocybin.
As you noticed by Pandora's response (whom is part of the welcoming committee as I try to be, because I know what it's like to be new) this place is certainly different, and in no way like Reddit. We practice harm reduction here, we encourage the growing/cultivating/extracting of your own medicines, and we focus more on quality posts and family.
For sure it's like any other forum, we're only people, but our mission here is to strive for professionalism and empathy. I've only been active on the forums for the better half of 6 months and I certainly feel like family here. I care about this place, and with conscious effort one day you will too!
Also, as far as Cubensis dosing goes. Out of my 75 or so trips I had, half were 1.75g for a lighter trip like going on a hike, and 3.5 grams was for intense solo trips, listening to music, painting etc. I've never exceeded 4g as I felt it was a little too intense for me, but everyone is different, so like Pandora said, working your way up is a smart way to go. The difference between 2 and 3 grams is substantial from my experiences. So 1 gram, then 2, then maybe 2.5, then 3 and then 3.5. Most people find their happy place at 3.5, but this always depends on the strain and how potent that particular strain was bred to grow. Sorry for the rant! Hope it helps!
Welcome and be safe. Ask all the questions you want. That's what this place is here for.
