Sorry, I really need help. I don't have anyone around so any word from you can be helpful.

Today, In online lab meeting, my boss said that the name of my two postdocs are in two different grants and our technician is in both but he did not take me into account as his postdoc. He then asked me, are you going back to your country? I told no please don't kill me and everyone simply laughed. I am in 18th months of my employment as a postdoc with him and my contact is until December 2021. His today statement has been a hug pain by which I have lost myself totally. I admit that after few months of my employment ,from his body language and all reactions I realised that he is not happy with me, he is not taking me serious, he is not eager to listen to me...

Do you think it is logical if I ask a private chat with him and request him at least he please pretend that he is happy with me until the end of my contract? because by each lab meeting I become such a frustrated and desperate that I have found myself in a pure darkness of hopelessness. In the morning turning the Teams app to see my colleagues who they are all happy gives me a feeling of death. I can not change myself, I can not increase my intelligence, seeing them when boss cherish them makes me hate myself and all my day like a nightmare
