Yes to all of those except for the startle response - I'm not jumpy at all. I'm too damn tired to be jumpy.
Before this started I'd have energy in the morning but crash in afternoon - now it's evolved to the point where I'm constantly in that crashed-state from morning to night.
I feel I should mention I did MDMA at the start of this year (new years eve) and after I came down it put me in a hyper-anxious state for about 2 weeks where my resting heart rate was 120bpm just lying in bed and I couldn't eat solid food because my digestive system was frozen. It was a constant intense adrenaline rush, like being on a roller-coaster 24/7.
This eventually went away and I went back to normal.
I didn't mention this in my original post because I was fine until a few weeks ago, aside from some afternoon tiredness.
