Feeling completely stuck and lost in life. Don't know what to do going forward.

I (32M) am working a government job 1000 km away from my home. The last 10 years of my life after graduating college have been a blurr. I graduated from a tier 1 engineering college but couldn't get placed due to low academic score, no marketable skills and my own asocial nature. And did not make an effort after graduation to go the private route.

Spent 4 years preparing for useless government job exams and finally got into one in accounting. The pay is mediocre and the work is mostly pointless. I feel completely stuck here. I always loved Science and wished to work in science or tech, even coding would do.

But now I feel like I am too old to switch but also cannot imagine myself doing this for the rest of my life. The worst part is I cannot even get transferred out of this state in this job. Which means I am geographically stuck as well.

Because of all this I've been avoiding my own marriage which ideally should've happened 4 years ago. Not that I have any great prospects anyway but the life of a recluse did not afford me a lifelong romance and I don't want to go the arrange marriage route unless I figure out my career.

Except I don't even know what to do or how could I change things. I wish there was some door or Avenue for escape.
