Hey y'all. I'm having some job issues related to being highly sensitive, so would y'all mind helping me brainstorm?

So, here's the deal. I'm 25, and I've run the gamut in entry-level jobs. I've had cashier, cash office, pharmacy tech, fast food, and admin experience. None of those were a good fit. I'm smart enough, but I get easily frazzled in fast-paced and high-pressure jobs. The admin job was quite the opposite, as I basically sat at a desk all day waiting for the phone to ring and maybe stuffing envelopes. I was bored stiff. My last job was at a library, as a shelver page. I loved the peaceful atmosphere, and I loved my coworkers, but again - bored. As a page, I wasn't really supposed to talk with patrons, which I like to do - just not in a high-pressure environment. So, I ended up taking a job at a coffee shop, as a barista. I've had some emotional growth in the last couple of years, and thought I was ready for this. It's been 2 months, and I still get frazzled easily. My manager had a talk with me the other day, asking what they're doing wrong that I'm not catching on. The worst part of all this is that I quit my job at the library 2 weeks ago, thinking I was ready to move on to something more challenging. I was going to re-certify for pharmacy, and try to work that and the coffee shop together. But now, I'm starting to rethink that.

To top it all off, I tend to be independent-minded, and hate being told what to do or micromanaged. Tend to be laid back. Take criticism very personally. Hate sales. Am soft-spoken, poker-faced, and very introverted. And am very sensitive - to the point that I have teared up in front of a couple of managers (despite my best attempts not to). I'm the type that would nearly faint if I saw someone else cut their finger. I recognize that I'm still pretty immature and have some more emotional growing to do.

All that said - any suggestions for entry-level jobs? I'm capable. I have some experience. I like working with people. And I have a bachelor's in business administration (which I'm pretty sure was the wrong major, in retrospect - I actually am not business-minded). I'm creative, and a really good writer - but don't have experience or a degree in a creative field. And I need a good job now.

Any ideas would be so appreciated!!!

P.S. - I thought about going back to the library, but I need a full-time job, which that was not. I'm having an awful time finding full-time work in an environment that's workable.
