I still love my job but it has changed a lot over the last 10 years. I started out in a rural community where the station did 700 calls a year (working as an EMR which is essentially the same as an EMT - B). Presently I'm most of the way through a Critical Care Paramedic program and working fixed wing/rotary air-evac (CCP programs are a Canadian thing involving roughly 5 years of post secondary education and a tremendous amount of clinical time). Every once in awhile I do get to be the cog in the machine with the ability to prevent disaster for someone. That part is an incredible privilege.
The give and take in this job is not to be underestimated. Paramedic education programmes are rigid/inflexible as a rule. I've missed numerous family events and important happenings as a result. The tolls that missed events, long stressful shifts (particularly nights), and in your case as a US citizen lousy pay, take on you add up. I know without question my life will be shortened as a result of my service. Think long and hard about whether the increased mental health risk, increased heart disease/stroke risk, and shortened life-span are acceptable trade-offs for doing this job long term.
