Your post really hit home with me. I am so analytical & weigh the pros & cons of every career decision too. Ive become paralyzed by my indecision to become a Nurse. The commitment scares me & Im really dragging my feet. I applied to Nursing School 3 years ago & then got scared. I then did a Medical Transcription study at home. I disliked that & never finished the program. Since graduating high school many moons ago I have weighed so many careers. (Elem Ed, Nursing, Pharm Tech, Medical Coder, Medical Transcription, Loan officer, etc...)
I took a personality test to determine a career path. Turns out Im an INFJ (Introverted / INtuative / Feeling / Judging) - "As an INFJ, your primary mode of living is focused internally, where you take things in primarily via intuition. Your secondary mode is external, where you deal with things according to how you feel about them, or how they fit with your personal value system" Wow that was an eye opener.
I too have been through mild depression because of my indecision..... Its so hard & scary to settle on one career choice. I can honestly say of all of the careers Ive research (a ton) Nursing offers a huge spectrum of possibilities. I currently work in a ICN Nursing Unit as a secretary & the nurses I work with love what they do. They have so many opportunities available to them & tons of opportunities to make extra money (shift diff / CE's) You never quit learning as a nurse. I also feel that once you start caring for others you will take the focus off of yourself & wont doubt your decision as much.
I need to take my own advice when I say commit to it & endure the hardship.
