I told my doctor yesterday about some symptoms I've been having every once in a while since I was a teenager (ten years ago :P) that have been happening more frequently of late. When I try to go to bed at night, it's like my heart just won't slow down, it keeps going faster and faster, and then I start to feel sick to my stomach and generally like I'm going to die. Sometimes I will throw up or have other "stomach issues". It has happened four times in the last month.
My doctor says this sounds like panic attacks, but I don't understand how I could have panic attacks for no reason... don't these things generally start with being worried about something or thinking particular disturbing thoughts? And why always when I try to go to bed?
I have had social phobia and panic attacks in the past, but usually stemming from thinking about particular things. Can it just happen for no reason?
