For the past one week, I cannot sleep. I try to sleep, and with great difficulty when I do sleep, I wake up in one hour. I have no other symptoms of note apart from extreme weakness and tiredness. I should mention that I had moved to another country across time zones, but was doing okay for the past 2 months. These problems only started a week back. However, earlier, I was sleeping quite late and waking up very late as a result. I am quite scared I am going to die. I literally cannot sleep for more than an hour a day. Please help me- what could it be? I am 27 years old and never suffered from insomnia before.
