There is a really wonderful Buddhist center in Vienna affiliated with the same branch of Tibetan Buddhism I have gone on retreat with. They should have retreats as well. I recommend checking it out. https://gelugwien.at/
Many nootropics will greatly amplify the feelings of depression (by personal experience and anecdotal experience of others). This may be because many of these substances interact with neurotransmitters like choline. Excess choline can lead to depressive-like symptoms.
That said, many non-nootropic supplements can be highly effective for depressive symptoms. I love 5-htp for a temporary serotonin boost. I use it for 2-3 days at a time until my mood improves.
As far as nootropics go, his choices are on the conservative side. Racetams have a relatively good safety profile, and Choline is naturally found in common food.
I don't see this being good for anyone in the long run. It enables the user to avoid a difficult, but important conversation. It's a generally held opinion that breaking up over text message is disrespectful and tacky, and this is even worse than that to me. The generic responses send to the person on the receiving end are likely to be hurtful as well. Better than ghosting someone I suppose?
