Hi,
I have recently been through a bad time having to have medical stuff done. And I got myself into a terrible state about it.
Now all the tests are done and I don't have to be nervous anymore. During that time and since then I have developed this weird feeling every night. I start to drift off to sleep and then jump awake again as if I forget to breath, it's quite scary and I am now finding myself nervous of going to bed.
Crazy thing is I do fall asleep eventually, so I must be breathing.
