Not sure what to do....

Ok, so I am feeling extremely confused, discouraged, and very desperate. I guess I just need a place to vent, and maybe to hear some words of encouragement or maybe some similar situations any of you have had. So here is the deal:

I have a bachelor's in biology and spent several years working in a lab. My job became monotonous, offered no benefits, and I wasnt making much money, plus I had an hour long commute each way. I thought about other paths to take and decided to give nursing a try. I spent over a year thinking about it, then spent a lot of time and money taking 2 pre-req classes I needed. I mailed my application and spent 3 months in agony waiting. While waiting, I unexpectedly was laid off from my job, but received my acceptance letter 3 weeks later. I was thrilled and felt relieved. I then spent the next 5 months searching for a job that would work with my school schedule. It wasnt easy and I didn't find anything until a few weeks before my nursing classes started. I found a part time weekend job.

I started nursing school expecting it to be overwhelming and hard, but expecting it did not prepare me for it. I withdrew after a month. I was so unhappy and I don't feel that I have a passion for nursing like all of my classmates did. I was doing good grade-wise, but I was miserable. After withdrawing, I started my job search again, this time looking for full time positions. I recently had an interview for a dream job, but just found out today that I did not get it. I feel so devastated! At this point in time, I have applied to over 150 jobs.

My part time job (which pays a LOT of money) isn't going so well, because they never put me on the schedule. I have learned that the position is really PRN, to basically "fill in the gaps" when the full time employees dont sign up for overtime on the weekends. I haven't worked in a month, and my finances are reflecting it. I feel so low and depressed and feel like giving up. There aren't many jobs around where I could use my degree, and I feel like trying to get a job is like trying to win the lottery!

I have looked into a local medical technologist program and I plan on applying for next year's class. I plan on shadowing some MTs for a few months to really get an idea of the profession. But I love being in a lab, and I really want to be in healthcare, so I think this profession might be a good fit. I did not know about this profession when I applied to nursing school, if I did I am 100% positive I would have not given nursing another thought.

I feel so desperate now for a job, that I am considering reapplying to my old program, or even applying to a different school's accelerated BSN program. I dont think this is what I truly want, but I am afraid I made a crippling mistake by quitting nursing school. Maybe its not my "dream career," but what if it was really my best option??

I know this is ridiculously long, but I feel a little better just typing this out even if nobody responds or reads it. This is definitely not how I pictured my life at 28 years old. And I am afraid of making decisions out of desperation. I guess Im wondering has anyone been in a similar situation? Maybe unsure of their profession, or if nursing was the right path?
