Routines
??. There are multiple things, so let's address stepwise. Essentially, your concern seems to be, daily routines have deteriorated the actual goal in career.
But let's accept one thing clearly. None of the goal in life is immediately achievable. You seem to loose patients, hence you also might tend to loose the direction.
"My office is 50km.." Daily routines are to be seen(or made) useful rather than burden. If reducing 50km travel is not practically feasible, make the journey useful (or at least think in those direction).
"..with no substantial growth.." The only conclusion is, despite of you worked for 8 hours a day, there is no substantial growth. Instead of blaming the system around you, look into yourself deeply and where you can make changes. while doing so, accept the fact that "substantial growth is not immediate"
"This has made me physically & mentally weak."
