We landed approximately 30 minutes early into ZZZ and our gate was not open. The Captain turned off the seatbelt sign and made a PA advising we would be waiting for approximately 25 minutes and the passengers could use the lavatories.After opening the first class lavatory; I phoned the Captain and verified the duration of our hold.  Sometime had passed and from my jumpseat; I utilized an app on my phone and did not realize my actions until several minutes had passed. When I realized what I had done; I was sickened and guilt ridden. Moreover; I was stunned over how automatic and mechanical my actions were without even thinking.In trying to make sense of what I had done; I began questioning myself and realized just how tired I have been from not being able to sleep throughout the recent nights because of stress over current events; specific to our COVID-19 world pandemic; our nation's turmoil; and our carrier's future without the cares act. Nonetheless; with over XX years of experience in performing my duties; I expected more from myself and am extremely embarrassed over my loss of focus; thus the reason for my report. It is my sincere hope that this event may help others.  Please know; I realize my actions were wrong and I take complete and full responsibility. In addition; this event has made me realize the importance of maintaining my focus at all times while performing my duties. To say this was a humbling experience would be an understatement. In closing; again; it is my hope that through this report; it may serve in assisting others in maintaining their focus at all times.
