A form of the pronoun 'them' used when referring back to a non-gender-specific singular person.
If someone wants to express their feelings, they should talk to themself about it.
The word 'themself' is a reflexive pronoun formed from 'them' (from Old English 'þā', meaning those) and the suffix '-self' (meaning oneself). It is used to refer back to the subject of the sentence, emphasizing the individual identity of the person or people referred to by 'them'.
Think of 'them' as referring to a group of people and '-self' as emphasizing individuality — 'themself' means that individual person from that group.
