Try to stay calm and think about your current situation, and what effects any decisions you make will have long term, it is easy to make bad decisions when you are in a bad state of mind.

Even if you leave your current job, nothing guarantees that the next one will be better, and it might sound easy to leave everything and go back to your home country, but you will miss a lot by living in the new place for just a short time, the best thing I can think of is to try to talk to your manager and tell them that you are not happy about the way that they communicate with you, and even if you are performing badly that they should inform you about that and what you need to do to improve in a less offensive way, some people will change their behavior once they are confronted, hopefully that will make them treat you better in the future.

it is hard to offer any advice without any more information, if it is only your manager/team then maybe consider switching to a different team, if it is a company-wide thing then probably it is best to leave, check you current visa/status and see if it is easy to change jobs, if not then think(with a clear and calm head) about whether you can stick with your current job until you can change it or not, and what any decisions you make now will mean down the line.

one last advice if you decide to stay with it, being in a bad workplace will affect you mentally and that might have an affect on your life and relationships outside of work, try to minimize that and keep all of this at work.
