Am I the only one who deals with this???

For context, I have been with my legacy airline(DL) and almost hitting my 2yr mark soon. I live in base, single and for the most part, im doing pretty well. I’m making pretty good money and love my job. I can truly say, I honestly don’t see myself doing anything else. I love my job😊. The problem is I have noticed my temper has been extremely short lately lol, Or maybe for the last couple of months. Typically I’m a very bubbly, social type of person. I get along with 98% of my crews. However, from the hectic boarding process to the beverage service, I feel like I’m constantly trying to keep my cool, I feel like im constantly having to deal with a passengers shitty personality or entitlement. People rolling there eyes at you, saying the rudest things ever to bluntly ignoring you while your doing service. I visited my mom during the holidays and she actually brought it to my attention. She pretty much said I had a short temper and I wasn’t like this before. I realize dealing with passengers on the plane has caused this automatic hardness in me that I don’t like. I want to know ways my fellow FA’s get through work with a smile on your face. I want to get back to my friendly, bubbly self while dealing with our passengers. Any advice is greatly appreciated.💞
