Just dropped! Advice for a therapeutic session?

I got a small amount of LSD at a festival a few months ago and it's been sitting in a drawer since. I've been feeling depressed lately and have had therapeutic experiences on other psychedelics, so decided tonight I'd try a tiny dose, by myself. This is my first time using LSD, so I took a dose so small I'm not sure I will feel much of anything but.... I'm nervous! Didn't really plan to take this alone when I got it, but it just seems like the right time.

Any advice from solo trippers on how to get the most of this, and what to expect, given my intention?

EDIT: Thanks for the tips guys! Looks like the stuff I had was either bogus or got ruined at some point because nothing happened :( Really excited to explore some of this stuff when I have the real thing though.
