It has nothing to do with being lazy or not taking responsibility. Being 'stuck' can be about being stuck in the past or some horrific memory and unable to get out of it. Quite often people will get stuck with PTSD and be stuck in a memory where the past replays over and over again. It also happens with depression with not being able to move forward, unable to get out of the misery. With anxiety it could be having panic attacks over and over again but not able to do anything about it.
