what should I do to help myself?

I've been having some serious problems lately. I lost my period this month. I can't sleep until very early in the morning, I can't concentrate at work, and feel exhausted all the time. I also have excessive hair loss and continuous migraine to the point that I feel like I'm going crazy. My work result has been horrible. Sometimes it's like I have the memory span of a goldfish. I don't know what to do now. I feel so useless that I think it would be better if I died. What's happening to me? Is it just stress or something more serious? And what can I do?

Obviously you need to get a proper diagnosis from a Psychiatrist (NOT MD DOCTOR)

But, as a sufferer of severe depression and anxiety, you pretty well just described the exact symptoms of clinical depression. And yes you are correct, It feels like a living hell.

Get some help. Get in to see a good Psychiatrist. Try to avoid letting a regular MD treat you for this. You need a highly experienced specialist such as a Psychiatrist to get proper treatment.

A regular doctor can and will attempt to treat you, BUT you do so at a VERY serious risk.
