Unwelcome obligations, also known as onuses, are tasks or duties that one is obligated to do but does not want to do. They can be seen as a burden and can cause stress and anxiety. Unwelcome obligations can range from small tasks such as cleaning the house to larger tasks such as taking care of a sick relative. Regardless of the size of the task, unwelcome obligations can be difficult to manage and can have a negative impact on one's mental health.
