It is getting worst. I like my own company.

I work in an office where everyone does not shut up for a minute. Constant talking and honestly I do not know from where they bring out conversations from. Me on the otherhand I am quiet and do not start a conversation unless I am spoken to. Recently I tried to start conversations but I get overwhelmed easily. On the otherhand silence makes me overthink what the other person might be thinking about me not having anything to say. Honeslty you can feel the tension in the air. It is getting so bad that by the end of the shift the other person tells me to leave early. I do not know if they are doing it with good intensions or because it is awkward that i have nothing to say and maybe they find it hard for them too to start a subject/conversation with me. Honestly i dread going to work knowing i feel like an outsider. Anyone feels the same and would like to share their story?
