romantic_thi3f has provided a number of good ideas for you to follow up on.
You mentioned you "enjoy things regarding the health system" but the courses could not be done totally online. What sort of courses were you looking into? And what part of the courses or how much was not online? My guess is the practical elements. But it might be worthwhile to ring up the places you have looked at and have a chat to them over the phone? And it might only be for a few days every term. Would that work for you?
I am unsure of this would work for you, but have you also considered study part time if you are worried about the financial aspects? I was doing a BTh which I have put on hold, and now doing a Dip. for a change of career (hopefully). Also, these days (at least since I was studying there is also HECS where the costs assoc. with study are deferred.
Finally, you could also do is find some sort of related to the area that you want to get into as a stepping stone. By analogy, supposing a person wants to become a programmer but does not have the skills. That person might be able to start in support initially while studying. Either when a position opens up, or perhaps elsewhere and they have their qualifications they can do programming.
Also and depending on the area you are looking at, TAFE might be a good choice also and give you the necessary qualification. My niece works in childcare having done a number of certificates through high schools and after.
In my opinion if you can
(1) work out what sort of job in the health industry you are interested in
(2) determine required qualifications
(3) what institutions will give you those qualifications
