Thinking about changing career path

But feel like I'm stuck.

So I'm a SAHM to 2, my timeline has been planned out, while I was pregnant with my first at 18, I started accounting classes, studying from home and I'm in my 4th year, when I finish this I'm moving onto a higher one, degree level in finance, using my accounting qualification as a fast track because I don't have any other good qualifications (if I didn't do 4 years of accounting, I would have needed good high school grades, a levels from college, basically a straight A student which I am not).

By the time I finish the degree level in 3-4 years, my youngest (6months) will be old enough to be in school and I can start working in finance, atm we are living off my partners income which is nice, but it's good to have my own career and more money you know?

So that's been the plan since I was pregnant with my now 4 year old and I've been following through with it.

I chose that career path because I'm good with numbers, always have been, even though I failed everything else in school, I got an A in maths and a distinction in health and social care which is also equivalent to an A (this one matters for this post).

When I was younger I dreamed of being a nurse or a doctor, wasn't sure which but as long as it was in a hospital, then a family member was in hospital for a couple weeks and when I would visit I would watch the ward nurses amazed at what they do.

Idk where that dream went 🙄

Now my youngest spent the passed week in hospital, I stayed with him 24/7 and the nurses trusted me with alot during the stay, showed me how to put antibiotics through his IV, getting his stats (BP, oxygen levels etc), bandaging him (only bandaging his cannula so it's safely tucked away so he doesn't pull it out), showing me how they get his medication ready and letting me have a go, I actually felt like a student nurse, the nurse in charge was good with it, I actually asked her first if I can be involved with it.

I enjoyed every moment of it and it reignited my dream of being a nurse.

Sure my future expected salary would decrease by alot, but now working in finance seems so boring to me, but I don't want these couple years to be a waste, I don't want to start from the start again and work my way in college to get the starting grades to start medical school.

I was thinking to go through with the finance stuff till we have the life that we want, buy our own house and create a comfertable life, then start thinking about medical school when I'm older (I'm 23 now) but picking up my textbooks is hard now 😩.

What do ya'll think?
