Normal people who don't have a cold don't need to take cough syrup.
It's precisely because being depressed is an atypical state that you need to take special approaches to deal with it.
What is not normal is sitting in front of some app, taking micro doses of LSD and 'meditating' in some stereotyped new-age fake-hipster-American way.
For normal depression for normal people it is possible to meditate without the LSD and the feigned posture. What you do is you go outside the front door and walk, ride a bike, go for a jog or go for a swim. Sure these normal activities do not have the pretence of the believe system that goes with mindful-LSD-taking but, for normal people with normal depression (including the suicidal thoughts), normal healthy activities can help too, e.g. a gentle stroll with no funny meds needed.
I think you're reacting negatively because of the commenter's association with LSD. That's not representative of the mindfulness practice in general, so if that feels a bit too "Berkeley" for you then don't throw away the baby with the bath water. Personally, I've never tried LSD, and although I'm a bit curious about it, I've read accounts of people being mentally crippled for years by a bad trip - not worth the risk.
How do you leave the house when you are depressed?
