Hello. For context, I am in a university. I do not have any friends, and it feels like colleagues talk bad about me. This makes me quite hesitant to join any circles or attend seminars. I am not sure it is everyone who thinks bad about me though, I fear about asking. Yet I plan to do research, so I should attend seminars to learn current trends and stuffs. May I ask what I should do in such a situation? Are friends necessary, or not really? Also should I stop being in this environment and get a job instead? Thanks for reading lengthy paragraph, I would love any comments or advice for this.
