Well I'm managing for the time being. I managed to get a job with the same company that I will keep temporarily. (It pays 3k less and includes more work, pressure and responsibility.
I'll stay there until I learn to drive. In the meantime, I'll learn to cope under that pressure and use any opportunity to learn whatever I can from them.
Then I'll find somewhere else to work.
(Not because I'm not loyal to them, it's just that I can see the same thing happening again further down the line).
Best of luck!
