MAN I SCREWED!!!!!!!!!!!!!!!

I know I have not posted in a while but things have been crazy at and home. First, I went to Eureka, CA. to help open a new Target. I was gone for three days. I loved it up there. I went out there with a good group of people to help out that store. The team from the Eureka Target was so thankful that we came to help them. They was willing to learn and work together as a team; something that is missing from my store. I really missed working in that type of environment. Our team had a great time there. Best of all, the district office paid for our rooms, food, and expense: so we charged everything to our rooms. But, I had to come back to my own messed up store. First, I get into a fight with a good friend of mine, at work, because his team screwed up my department while changing it around and he blamed me. They left aisles empty; garbage everywhere; just work undone. When I went to him about these problems, he blamed me for not help his team. When him and I was planning this reset out, I asked him if he wanted my help; he said "yes". Then, I told him that he needed to talk to my boss so that I could be scheduled to help him and his team. He asked once, got no answer, and did not follow up on it. But, it is my fault. I got angry when he said I was not a team player and the problems was my fault. I yelled at him. I was wrong for the way I reacted. But it pissing me off when anyone say I am not a team player. I help any and everyone that needs and asks for it. I push freight that is not mine. I help watch the cashiers to give breaks to supervisors there. I have pushed carts and help guests out of the store. I have help the security team subdue shoplifters. I have watched the phones when needed. I have helped out in other deparments when asked. I have done everything that have been asked of me. 90% of the people in that building would not do 10% of the things I do to help out. But I was that I was not a team player. I am sorry that I got angry at him. But he did not want to take responsibility for his team and their mistakes. It does not help that work has me stressed. I help train my peers. I am ready training one new supervisors for two weeks, but they decided it would be funny to have me start training a new one. So now, I have to come up a way to starting a new guy without going over the same stuff I taught the first trainee. Man, I am screwed. On top of that, I am that only Team Leader (supervisor) on my side of the store, because they fired one guy, another guy is on vacation for ten days, and they have not hired anyone for the two spots opened. So that means I have to take care of a whole side of a store while training two new guys. On top of that I have to figure out a way to patch up things between me and my friend. MAN I SCREWED!!!!!!!!!!!!!!!
