Yesterday I hung the new picture on the wall.
When 'hängen' (to hang) describes an action, it needs an accusative object (whom or what am I hanging?). When it describes a state, it is intransitive and has no accusative object.

He hangs his jacket (accusative) on the coat rack.
In the emotional meaning, 'hängen' (to be attached) is always used with the preposition 'an' and the dative. The structure is: 'an jemandem/etwas hängen' (to be attached to someone/something).
Er hängt sehr an seinen alten Büchern.
He is very attached to his old books.
The meaning 'nicht mehr funktionieren' (to stop working) is colloquial and is used almost exclusively for computers, software, or internet connections.
Das Programm hängt ständig, ich kann nicht weiterarbeiten.
The program keeps freezing; I can't continue working.
The expression 'sich hängen lassen' (to let oneself go) is reflexive. The reflexive pronoun 'sich' must be adapted to the subject of the sentence (ich lasse mich hängen, du lässt dich hängen).

After the disappointment, you mustn't let yourself go like that.
