深情只是我担不起的负担

In many situations, the word means that having a profound love is a heavy burden that you carry within you. You're bearing so much affection but might not be able to express it properly due to circumstances; thus turning such depth into something difficult and cumbersome. For some users, this may imply unreciprocated romantic feelings or intense emotions that aren't understood or accepted by the intended recipient, resulting in more internal struggle than anything beneficial.
