sucking-fluids's journey

I am currently applying for two entry-level positions at a local hospital: one in respiratory therapy and the other in housekeeping. Since this would be my first job, I'm feeling a bit lost on how to write a cover letter for both roles. I've been searching online for templates but haven't found one that suits my needs. I plan to check Microsoft Word for some options to get started. Any advice on what specific details I should include in my cover letter would be greatly appreciated!
