Constant anxiety and pounding heart.

Hello, The condition described by you here is suggestive of significant mood and anxiety disturbance. Which could be a depressive episode, panic disorder, generalized anxiety disorder, may be related to your social environment, or due to some underlying medical condition like thyroid, anaemia etc. Hence a comprehensive assessment is likely to be required before commenting any further. Hence I would suggest that you seek a consultation with a psychiatrist near you for comprehensive assessment and evaluation. Thereafter a detailed management plan can be formulated for you... However please be well assured that your condition can be helped and relief can be provided once you seek help. Usually a combination of medication and psychological intervention is likely to be management of choice in such background.. Hope this helps you, best wishes for your health and future..
