I think I might have an anxiety disorder

Hi guys, it's my first time posting. I think I might have an anxiety disorder.

I am constantly scared that something(crime, natural disasters) might happen to me or loved ones to the point where I get really panicked when my husband stops at a red light.

Last night, I was literally crippled with fear in bed, i couldn't sleep, was shaking, racing heart. Its more dominant at night, any sound I hear at night causes extreme panic and im entirely convinced that its a possible breakin, a tsunami/tornado or that something bad is about to happen. I get 3-4 hours sleep a night because of this.

Do i need to seek out help?
