Can severe chronic anxiety and panic attacks be critical to your health? as in cause aneurysm or brain hemorrhaging? (23 old, female, good health)

Yes and NO!: Anxiety has no immediate consequences in terms of affecting your health in a serious way.... yet its effects on your body are like chronic stress which in the long range could have some detrimental effects (no aneurysms etc). In order to better your health, you should institute 2 changes in your lifestyle which will cut down/eliminate anxiety.: Exercise(take a morning walk) daily and learn torelax

Feels, but not: In a healthy individual, panic attacks are not dangerous, although they feel that way. A Harvard study(2007), found a link between panic attacks and heart risk in postmenopausal women. This link has not been clarified, but a recent Australian study (2015), suggested that, in some people, the symptoms of panic attacks might represent a musdiagnised heart condition, but again, highly unlikely.
