Dosing psilocybin

I haven’t been in the best headspace lately and have been feeling a bit depressed. I’m considering a psilocybin trip with more of a therapeutic/introspective intention rather than just a recreational experience.

For those who have used mushrooms with a similar intention, have you found that a moderate dose can still provide meaningful therapeutic or introspective benefits, or did you feel that a higher-dose experience was necessary?

I was thinking around 2.5g, but I’m interested in hearing about people’s experiences with different dose levels, mindset, and setting—especially when going into it during a difficult emotional period.

Not looking for medical advice, just personal experiences and perspectives.
