I usually don't have much trouble with anxiety, so all of this (read below) coming on suddenly has been quite overwhelming and frightening. Note: I have not changed anything about my daily routine (no new meds, I don't do drugs, or drink). 

Last week I started not being able to sleep well and noticed I was really irritable. I stayed up until 4 am. Then a few days after that I had constant adrenaline dumps the entire day for no reason (I wasn't thinking anything bad). I've never had that happen before; usually I always have a reason for my anxious feelings. Then I started to get really bad insomnia (I'm staying up until 6 am and sleeping until 2 pm). Then on top of all of the adrenaline and anxiety I started getting derealization (nothing seems real and I have sensory overload). I made the mistake of googling insomnia, derealization, irritability, and anxiety and of course I saw all kinds of worse case scenarios like schizophrenia. So now I am terrified I am going to have psychosis or get schizophrenia. The adrenaline dumps won't stop. I'm literally experiencing them from the time I wake up until the time I go to sleep and no matter how much I try to reason with myself, they won't go away. I can't stop worrying about my insomnia (which only makes it worse) and I can't stop worrying about my derealization which makes that worse too. I feel like I'm in an uncontrollable unending loop of anxiety, derealization, and sleep deprivation. My doctor can't see me until next week and I am terrified that things are going to get worse before then...especially since this has never happened to me before. Has anyone else had something like this happen? If so, how did you cope? Are there any websites or Youtube videos that have helped you calm down? Thank you!
