Issue with Trainer at work

I have a meeting soon to discuss several issues relating to a trainer to my boss and higher heads. I am training under him to maintain and fix medical equipment. He is an older man and im in my late 20s. It can be difficult to work with him at times because of language issues...his first language is spanish..Cuban. There was a time when he gave me the job to put a calendar on a wall and said women should put calendar on the wall which made me laugh and he pointed his finger at me asking "You laughing to me? You laughing to me?" Another issue was where we were discussing the principle of how a device work and i felt misunderstood and he explained it his way and later asked if i was trained by anyone else before him and i declined answering him and he said everything i wanted was because he gave me and since i will not answer him to go and do research for.myself. There are many other issues and.im.just exhausted. I feel numb at work where i just dont care what happens anymore. Of course i cant actually say that in.the meeting but thats just how i feel.
