I was in a similar position, and will give you the advice I wish someone had given me:
Degree-wise, you're in a similar place to people with liberal arts degrees - you have a degree that proves you can learn, study, analyse data, communicate with others, write well, take information and act on it etc etc. You can apply for any graduate-entry job in any business or company. You do not have to stay 'in your field' - and if you try to do so you'll majorly limit yourself.
Write a list of all the skills that your degree and life have given you (not the subjects you studied - but the work-transferrable skills that you have acquired), learn job interview skills and self-marketing, and go get a job. Any job. Nobody expects you to stay in the same job for 10 years anymore - if you see a better job, then apply for it.
If you want to try programming, then do some - learn it online, write something and use that as experience on your cv.
What I did - BSc in Biochemistry (like you, had wanted to do med, but changed my mind), realised BSc didn't lead directly to a job (surprise!), considered teachers college but didn't want to be a teacher, didn't think I had any other options (wrong, but I was young and nobody told me otherwise) so did a Masters degree. Upon graduation, the only jobs I could walk straight into were lab-assistant jobs for low-pay, funded from soft grant money so no job security. To climb that career ladder I'd have needed a PhD. Not a pathway for high earning!
There are tons of careers, industries, workplaces out there. Plenty of scope for someone with ambition and ability.
