First of all, this is my first post so can I please say hello to everyone.

I am feeling very frightened tonight and for no apparent reason...I have been feeling less stable recently with regards to depression but my anxiety in the past has been focussed around a particular thing

I felt really tired all day but also really on edge and I have spent money I can't afford on line to distract myself and eaten too much junk for the same reason

Anyway I went to bed around 6pm (UK time) and woke up a couple of hours later feeling terrified like I was going to get hurt...I am really confused, I'm not normally paranoid in this way but I feel like I am waiting for a knife in my back

I feel really shaky and my heart is beating really fast like I want to run away but I'm already at home so theres nowhere to go to

Sorry for rambling, it doesn't feel like a panic attack more just like terror that I don't understand

Has anyone ever felt like this?
