Hi Ornela: I completely understand your situation! If you worked with professors on any outside projects, work study, internships over the course that you have been in school you can count as experience. I also, would suggest to go to the career service in your previous school for any partnerships they may have hospitals. Apply to temp agencies that specialize in the healthcare or science field. You also apply for contract positions in hospital and volunteer/ intern at a hospital. Research some hospitals in your area and find the head the department your interested in, email them with explaining your interest in the field and ask for informational interview. You can even as to shadow them so you can gain the experience you need.
