<human>: Give me the gist of the text in a nutshell

Ok, at the moment I am on my second year in university studying Joint Honours Japanese and Management (I guess it's something similar to majors in the American system? I'm not really sure). I'm not gonna lie, I chose this because I wasn't sure what I wanted to do with myself after graduating from school and Japanese was something I was interested in (I dislike management quite a lot but it just seemed like a more practical thing to learn rather than a foreign language alone).

Recently, I've been thinking about my choice more and more. I love science, especially chemistry, and was always good at it but got discouraged by a few teachers at school and dropped it. Now, however, I am starting to regret that choice and think that I'd feel happier if I was studying chemistry instead. I realise that transferring degrees at this point is not possible because they are too unrelated. Also, I (and my family too) have already put far too much money and effort in my current degree and I wouldn't dare to drop it now.

The biggest problem is that I can't see any kind of future with what I'm doing now. I understand that loads of current university students probably feel the same way. Still, the fact that probably for the first time in my life I figured out what I want to do but I can't do it bugs me loads.

So I guess my question is what would you do in my situation? I realise that I have two more years to study and so much can change over that time but some advice would be nice. Also, I'm abroad till June and I don't want to talk to my family about such a thing over the phone. 

If anyone had a similar experience I'd really appreciate it if you could share it too.
<bot>: version - thinking that I made a mistake when choosing uni degree, think it's too late to change now. Any advice?
