I don't know how to behave as a new PhD student towards the other people in my group. I started my PhD at the begining of Covid in February 2020. One week after I met the people in our group, our research center was closed. During the last year, only me and my advisor came to the research center. Others visited from time to time.
Now, restrictions were lifted and the other members of the group started to arrive. We know each other, but nobody invites me to anything, even lunch. Besides, my room is in another corridor and there is noone from our group on that side, it's just me. I can't see if the rest of the group is leaving for lunch or not. I feel so excluded and I don't know what should I do. I'm like a complete stranger. They don't have to like me, but I don't understand why they act like that.
There will be group meetings which I don't want to attend. Would it be bad to say to my advisor that 'I do not want to attend the meetings because no one but you has talked with me until now' ?
I want to add this, to be more extrovert, I did my best to bring cake and invite others for coffee.
