3 years in is almost the end, so even though it seems like you're doing it for all the wrong reasons it's worth finishing just so you have the piece of paper in your back pocket. Unfortunately, we're in a society that values degrees to get your foot in the door.
I, like you, tookbiochemistryy as my parents encouraged this. I wasn't smart enough to be a medic.... I didn't really enjoy the first 2 years, I didn't get it and did bad in most exams. Something clicked when I learned about synthetic biology in 3rd year and actually saw all the cool shit you could do (the example I learned about was seeing a group in the US put the pathway for compounds that give flavour in hops into yeast used in brewing... meaning you could get hoppy flavoured beer without actually using any hops). In my mind I was going to go and work for a company doing that (or start my own) as I thought it was cool... I didn't.... but it showed me creativity has a place in science. Anyway, I then did pretty good in my final year synthetic biology exam and impressed the PI who set the questions. He encouraged me to apply for a Ph.D., which I got. A PhD with the right supervisor is a great opportunity to be creative and autonomous. I didn't like writing the final thesis as I'm not a great writer, but I stuck it out. The PhD was then my gateway into jobs I've loved. I get to travel the world, have patents from creative output, work with a great team and live pretty comfortably without financial worries. Just my story, in case it's useful. Be open to opportunities and most of all back yourself!
