Thought i got fired…

On Friday i went to work, i started at 5pm and was supposed to work until 10pm. Shortly after I clocked in i was asking my coworkers if anyone could take my shift for Saturday because i had my friends sweet 16 birthday party that i could feel so shitty if i missed… no one was able to take it and my manager gonna call her M, M asked me if i had asked anyone and I told M that no one was available. She told me to figure it out cuz there was nothing she could do. I was getting pissed off and said,”whatever I will just skip the thing i have for Saturday.” I was frustrated and was venting to a coworker and was using strong language, M heard me and said let’s go talk in the back. We went to the back basically she told me that I cannot act like that or say words like that just because i was pissed off, she told me to leave whatever had me stressing and upset at home and not come into work with that. A few minutes later I was back out on the floor and then was saying how if i missed this party that i would be so dumb and said that I should k!ll ms. I did say more but that was the basic of what I said. A few minutes later M told me to go home and not come into work on Saturday, she said to call and ask for her. It’s been a few days now things have chilled, ive been trying to call and go in person but she is not there…. My last resort is to leave a not explaining things and telling her I would like to talk in person. So yea that is all that has happened im so confused right now….
