I am sure it cannot be easy for you to be in a place so far from home and staying with a manupulative and difficult boss. You must have signed a contract with someone when you started the apprenticeship - with whom was this done - if so, you have recourse to theis contract and possible protection. Is it possible to be fired duting an apprenticeship?
I don't know in what field of work you are, but would recommend the following:
Just relax and don't stress too much about pleasing him. Just do the job to the best of your knowledge and don't try to fit in with additional aspects - so many companies expect their employees to have certain social norms that go beyond work performance and skills.
Use whatever protection may be offered by the contract you signed when starting the apprenticeship, and check what they expect from you.
From experience I know how frustrating the work environment can be.
Try to spend some time alone from time to time during your spare time or weekends, even if it's just going for a walk or jog, or watching a movie or ball game, so you don't feel trapped.
Best of luck with this situation and keep us updated.
