Yeah.

As your example shows, constant change of environment (before you identity with the current one) and lack of uniqueness (makes it easier to form an identity) is one method. Disorganization (lack of structure) is common among depressed individuals. There must be no structure to life, nothing unique from one person to the next, one place to the next etc. to anchor the person's identity. Solve et Coagula.

Another method is to give hope and then yank it, and keep repeating that (eg: Trump gave hope and election fraud took it, Q gave hope and failed predictions took it, end of lockdown gave hope and more lockdowns will take it, vaccines gave hope for end of pandemic and vaccine failure took it etc.).

Another method is to drain your energy in useless social media fights, riots and other incidents designed to maximally provoke you etc.

But also be careful of too much Black Pill -> might lead to detachment and acceptance of "fate", nihilism, depression (not enough strength left to resist) etc.
