I feel stupid even asking this question but I can't help but stress over it.

My mom just told me some really bad news and I started crying. I was trying to suppress it at first but wasn't really successfull. Instead, I just started sobbing and jerking my head backwards with every sob. I could feel that it was hard on my neck but as you all probably know once you start crying it's hard to stop. So I continued sobbing and jerking my head every few seconds for at least a few minutes until I calmed down a little bit.

As you can probably guess, I am now really dizzy, have brain fog and a mild headache. I am wondering if I caused damage to my brain jerking my head like that or if it is just my neck.

I am so sick of worrying about things like that but I just can't help it. It really frustrates me since I would have never thought about it before my injury.
