<human>: In April 2012, I landed an Quality Assurance internship at a pharmaceutical company and I worked there until September 2012, when I had to leave for university. My boss was the branch director of the QA department and I had several supervisors while I transitioned through the different QA departments. 

My boss was really nice and everyone else was a pleasure to work with as well. We had a good relationship and I made a good effort to establish a pleasant relationship with everyone else I met too. I had very good work-ethic and most days I completed all the assignments so quickly that they usually ran out of tasks to assign me.

When it was time for me to leave the position, my boss treated me and the other supervisors to a very nice lunch. On my last day, I wrote her a letter expressing my gratitude and appreciation of the internship and gifted her with several gourmet/unique chocolate bars I brought back from my recent trip to Seattle.

I'm about to finish up my bachelors degree in pharmaceutical sciences with an expected graduation in March 2015. I'm really worried about finding a job and my self-esteem regarding such is rather low.
I was hoping to contact my old boss for career opportunities but  I haven't spoken to her since I left (over 2 years now).

I've gained a lot more experience (mostly as administration assistant, and IT related things) along with hopefully a bachelor's degree. I was hoping for any sort of position within the company (whether QA or QC).

I know we ended on a high note, but how would I open up that relationship to gain a career opportunity either within that company? Or possibly ask her for other company leads?

Can you give me the gist of the text in a nutshell?
<bot>: I had a good relationship with a boss from 2 years ago. Haven't spoken to her since. How would I reopen that relationship in order to ask her about career opportunities?
