have you ever worked in the care setting as a nurse or something before? have you tested your ability to deal with blood, urine, vomit, faeces at the same time as being shouted and cried at?
if so, welcome to the club of awesome, if not… get yourself some experience in the care setting before making a career change 🙂 the only way to know if you’ll be able to handle it is to try it in my humble opinion.
when i studied to be a nurse you could tell VERY quickly who had worked as a care assistant first.
dont let my post put you off though 🙂 i have a huge huge huge amount of respect for paramedics and its an admirable job to aspire to.
