Cold sore vs pustule: It may be a cold sore, which is common in young people and often induced with stress. Cold sores go away on their own, but they can scab and be painful. Can treat with soothing/numbing cream. Alternatively, it could be a ruptured zit or other skin infection that drains pus. If you already popped it, then apply antibiotic ointment 2-3x day like Bacitracin or neosporin, available OTC.
