"Burdened" is a straightforward option that implies carrying heavy loads, while "oppressed" gives a more emotional context of being weighed down by external forces. "Overwhelmed" is also a viable alternative for a person who feels like they have taken on more than they can handle. "Burdensome" offers a more descriptive perspective, focusing on the heaviness of the task, while "encumbered" provides a sense of being restricted by the situation. In any case, these synonyms all serve to convey a weighty sense of being "heavyladen".
