What The Heck Am I Doing?

I think I've had moments where I felt this way over the past couple months, but never more so than this week. I just keep wondering why I decided to move here and change industries and leave literally everything and everyone I've ever known. I have no one here. I have no support system. I have no friends. I have no business in the luxury world. My idea of luxury is buying soap from Bath and Body Works rather than Walmart. The idea of working in Luxury sounds exciting and I think most would agree. I think a lot of people would initially jump at the opportunity simply because it sort of encompasses the ultimate American dream. It's the industry that sort of defines "making it". I mean let's be honest...I was proud to tell people I got this job and I still am. But the more I've worked in it, the more I feel like I don't belong. Sometimes I wonder if I'm trying to hide from my feelings of inferiority by calling to question the shallow nature of the industry. I see people spending thousands of dollars on a tiny bracelet and I think about people starving in the world. I wonder sometimes if I'm doing this just because I'm trying to find some excuse for leaving. It's like in high school when you're an outcast. It's easier to say that the popular kids are shallow, superficial, and of low character(whether or not any of these things may be true) than it is to accept that a lot of people happen to like them and not many people like you. I don't want to be like that. I don't want to constantly be trying to find the flaws within my current position simply because I'm not succeeding at it. Unfortunately, I think that may be what is happening. I do think my natural interests lie elsewhere. I can't help but see a kid and want to talk to them or find out what they like or what they've been doing recently. Every time I see a teen retailer I think about the fun I had in my previous career and how I loved helping families shop for back to school. So I'm constantly questioning myself. Do I dislike this career because it's different, it's change, and I happen to be struggling at it or is this simply not my calling. I don't want to limit myself simply because something is hard. At the end of the day though, that is human nature. I think it's natural to resist change. I knew going into this it would be hard and extremely out of my comfort zone. To some degree that is why I took the position. I wanted to push myself and grow. I wanted to develop new skills and learn how to work in a different environment. I guess I underestimated just how hard it would be. Getting into the store has been the most challenging piece for me. I expected it to come naturally and it hasn't. In fact, it is one of the hardest things I've ever done in my life. I feel like my supervisor hates me and I've never felt more incompetent in my entire life. I feel like everything I do is wrong. I'm not sure what else can be said right now. I'm just sad and lonely and questioning everything.
