Many years ago I fractured my skull, was in a coma, was never recieved any support until recently as I researched the effects of my sons head injury
I noted that some of the symptons match what I went through and stlll do like anxiety
Is this mental health illness
Some people think brain injuries can be associated with mood swings
It is possible it could be post traumatic stress due to lack of counselling after the injury
People can have many problems after a head injury, depending on which part of the brain was damaged, such as damage to the frontal lobes can reduce impulse control, & make someone very difficult to live with because of behavioural problems.
Does anxiety cause headaches?
Does anxiety cause diarrhoea.
Does anxiety cause physical pain? If yes how to cope?
Mentally exhausted 😩 
Illness.
