I often use stuff like that to deal with inability of getting a romantic partner. I just gaslight myself into believing "this ship has sailed for me, it's better to accept it, I cannot be lucky with everything". This usually works well, except I still tend to develop a crush on some person (usually a VTuber - they're not normal people, and neither I am), which then pushes me into instant despair.
I was thinking about selling this tip to incels in some form, under the name "nirvana-pill", but I don't think they'd listen to it.
