Maybe I'm Too Sensitive...?

This is kinda hard to explain and maybe I shouldn't get so upset about this but at my work I was very excited to move into a new department, the cosmetic department (yay! ^.^), now I understand that I'm a novice since I've only been working there for almost a year, but don't get me wrong I'm a great worker. So, I'm about to go to the department and all of sudden this woman I work with starts screaming at me. She was like I don't want you in this department. You're no good. But I'm like, "The manager said that I could work in this department." And then the woman was like, "I don't care who said you could come here. You're a beginner. You're useless." And then my manager wouldn't let me into the comestic department. :'( The woman continued to yell at me even more. She was calling me all these names and stuff, saying that me going into that department wasn't right. And maybe I expected too much but I thought my manager would back me up. Instead he betrays me and agrees with her. I felt like she was beating me up with just her mouth. She hit me at my weak spot, she said, "I don't know anything about the department b/c I'm kinda new." I tried to act civil. I'm like, "It's ok. I understand." Secretly, I could feel the tears harden behind my eyes. And my chest tightened. So, this other person got put in the cosmetic department. I can kinda understand her but she didn't have to scream at me and freak out like she was possessed. And sadly...I think it really hurt my feelings. I felt like a glass that shattered all over the floor--crushed. I can't be an expert if you don't teach me. Or maybe I'm just pathetic to be upset over something so trivil. It was just so unexpected.

I told my friends about it, and they thought it was horrible. But I never mentioned to anyone that after holding back my tears at work and becoming overly defensive with customers that I cried when I got home. The manager knew that I was really upset when he'd catch me staring off lost in thought. And the woman embarrassed me b/c when she shrieked and stuff, almost all the other employees were near us. I was humiliated, degraded and underestimated. But I feel like that often since >I've been there almost a year but haven't been trained in any other department than the one I started in while everyone else has been trained in all departments. And when I ask to be trained, the managers blow me off nicely. And even now as I write this I'm just so angry. I was really looking forward to working in cosmetics. Sadly, right now I'm crying, letting the tears blur my vision, so since I can barely see the text...I'll stop writing.
