I am a fresh college graduate. I'm 21 years old. It was in December 2017 when I just felt this sudden sadness. And up until now, I am still struggling with this. Aside from that, I can't help but feel a sense of worthlessness. A gray feeling that never ends. Series of panic attacks happened to me since October 2018. There are times that I would just cry the whole day and have no plan of talking to people around me. Voices of unknown persons are also there. I keep on hearing voices in my head telling me that I am better off dead. I can no longer focus on my work since July 2018. I lost my passion. I just feel empty. I feel so lost. What should I do?
