I think one subconsciously knows what he/she wants to do, you just have to find a way to figure out what that is. It is always a good idea to observe or shadow someone in the field to know if you like it. 1 day is definitely not enough to see if you like it for sure, I would suggest following for a period of one week to see the actual schedules and what a week in the life of a healthcare professional looks like. Volunteering in similar fields like a nursing facility is also a good idea to get a better insight into it. If you feel forced, then maybe you wanna try it out first before making any decisions because it is a long and tiring journey, it is a mentally and physically draining job, the long hours you have to put into studying, and later long hours into work. So if you actually feel ready for it after shadowing, go for it because it is undoubtedly very rewarding in the end as well.
Hope this helps.
