Usage tips
Word structure
The verb is made up of 'er-' and 'schöpfen' (to scoop/draw). 'Schöpfen' means to take something out, for example water. So 'erschöpfen' (to exhaust/deplete) has the literal idea of taking something out until nothing is left—whether resources or one's own strength.
EXAMPLE
Wir haben unsere finanziellen Reserven vollständig erschöpft.
We have completely depleted our financial reserves.
Participle as adjective
The past participle 'erschöpft' is very commonly used as an adjective and means 'very tired'. The form 'Ich bin erschöpft' (I am exhausted) is more common in everyday speech than the active sentence 'Die Arbeit erschöpft mich' (The work exhausts me).
EXAMPLE
Nach dem langen Flug waren alle Reisenden völlig erschöpft.
After the long flight, all the travelers were completely exhausted.
Fixed structure
The meaning 'to be limited to something' exists only in the reflexive form with the preposition 'in' and the dative: 'sich in etwas (Dativ) erschöpfen' (to amount to / be limited to something).
EXAMPLE
Seine Hilfe erschöpfte sich leider in guten Ratschlägen.
Unfortunately, his help amounted to good advice.

erschöpfen vs mitnehmen
to take along / take away
'mitnehmen' and 'erschöpfen' can both express that someone has little strength afterward. 'erschöpfen' mainly refers to physical or mental tiredness: work, exercise, or stress makes someone very tired. 'mitnehmen' is broader and often more emotional. A sad event, difficult news, or a long illness can wear someone out. In that case, the person is not only tired, but emotionally burdened. When it is clearly about strong tiredness, 'erschöpfen' fits well. When an experience makes someone sad or leaves them feeling very affected, 'mitnehmen' sounds more natural.
erschöpfen
Nach drei Stunden Training erschöpft ihn jeder weitere Lauf.

mitnehmen
Der lange Streit in der Familie nimmt Paul noch immer mit.
The long argument in the family is still taking a toll on Paul.
