Burden

This can be a symbol for a person's sins or anxieties in life, Ps. 38:4, Matt. 11:30. A burden can also symbolize other people's problems, Gal. 6:2

The sense of having a burden can coincide with knowing you have to be somewhere 'but…' Whatever symbol arises that you are forced to hold on to or protect, while you miss something else, will offer clues as to how the past is adversely impacting your future.
