lasten vs drücken
to press / hug
'drücken' and 'lasten' can both express that something is heavy or difficult for someone. 'drücken' often feels more personal and describes a worry or feeling that burdens someone. 'lasten auf' sounds stronger and emphasizes the weight of a responsibility, guilt, or worry. It usually needs the form 'auf jemandem lasten' (to weigh on someone). If you want to say that someone is burdened inside, 'drücken' works well. If you want to highlight heavy responsibility or guilt, 'lasten auf' is more precise.
