Is that only me?

Is that only me? Who feels this kind of behaviour?

I recently joined a company and my trainer is making me feel different, I don’t know if it’s because I’m Indian, different than others. I am introvert specifically so I don’t engage with everyone that much but that doesn’t mean I have attitude instead I am like this only and I give my best to talk to my colleagues and saying good morning, bye to the trainer.

I started feeling it after 3 weeks of training and now it’s just getting worst. Whenever I seek any help the expression she gives that is worst, look like she feels angry or disturbed if I ask for help. Starts pointing out specifically my mistakes in the whole group and for others she just doesn’t focus on their mistake.

I think now she is planning something to get me out of the job as I looks like her main focus is me all the times. What I should do about this?
