The physical symptoms of anxiety are caused by the brain sending messages to parts of the body to prepare for the “fight or flight” response. The heart, lungs and other parts of the body work faster. The brain also releases stress hormones, including adrenaline. The following symptoms can occur as a result:
diarrhea
abdominal discomfort
dry mouth
rapid heartbeat or palpitations
tightness or pain in chest
shortness of breath
dizziness
frequent urination
difficulty swallowing
pins and needles
Psychological symptoms can include:
insomnia
irritability or anger
inability to concentrate
fear of madness
feeling unreal and not in control of your actions (depersonalisation)
think constantly about the worst outcome
become depressed and/or
become preoccupied with, or obsessional about, one subject
