Jobs in the medical field that require associates degree or less?

I don't think I'm up for a 4 year degree just yet, but I'm interested in doing something like an associate degree or some training or a certificate program. I've always been interested in the medical field (loved playing doctor as a child-splinting up "broken bones" and such).

Just looking for some ideas. I'm not easily grossed out or anything like that. I can really only work limited hours too because schizophrenia/bipolar and stress don't mix well in my experience. I can stand, walk around, sit, whatever, do paper work, for hours. I can do anything, just not for long periods of time all day every day of the week.

Right now I'm volunteering at an animal shelter and it's going well. It involves medicating cats and dogs as well as cleaning up their messes and feeding them. I've always been good at math and science, but I'm also a competent writer (published poet).

My peer specialist wants me to make a long term goal so I have something to aim for instead of just trying to survive day by day.

I'd also be interested in something like crisis intervention. Like one of those people who go in and assess people in the ED and decide if they need to be hospitalized, do PHP, IOP, or just need to follow up with a psychiatrist/therapist.
