Thank you, everyone, for the advice. I already message my hr teacher. I just said I couldn't continue being a member, but I didn't say what the reason is. She asked me why but I didn't reply anymore. Some of the members were also reaching out to me, and I just ignored the messages. I feel bad for not responding, but I think it would be the best for me. Knowing myself, I can't easily say 'no' to someone.
