I'm currently on my 12th day and till the day before yesterday everything seemed easy but yesterday I got a sudden headache in the right half and I became angry and moody for no reason. I also had an argument with my father yesterday and since then I'm not talking to him. I really want to apologize but something is just stopping me I don't know what. Moreover, I feel soo pessimistic that I was even thinking about suicide. I'm worried. Are these the symptoms of flatline or do I really need to go see a doctor. Need your help people!!!
