This probably won't help much at all but here's my experience.
I did a degree which I enjoyed - Computing Mathematics. I did an MSc also in Mathematics, and then came out of university looking forward to working hard, for lots of money. Of course now I'm stuck in a job which is interesting, and pays very well, but every day I realise it's not what I want to be doing.
When I was a lad (eg back in 't'day) I was at a specialist music school, training to be a pianist and was a chorister. I had an accident which ended my piano playing, and naturally my testicles left their warm snug place between my legs by a few inches, so I stopped singing treble. It's taken me literally 10 years to get back into singing, and I've been so so lucky that I've fallen straight on my feet at a highly renowned choir at a world famous university, having been a professional musician for 5 years (as a chorister), I would have hated any level of it that wasn't absolutely of the best quality.
If you don't enjoy what you're doing: change it. Hope that helps in some sort of fashion.
