Fear & Anxiety. Hi doctor.

Hi Doctor. Thank you for your time investment in helping patients. My father has been going through a lot of anxiety and this is what he has to say after having done a lot of introspection: I get fearful of tasks ( routine and at work place ), situations and people before interacting with them I'm feeling  too anxious , nervous , voice gets choked and feeble I feel very vulnerable , low in self confidence and self esteem , inferiority complex and depressed Earlier I wud get jittery with upcoming events but now the fear has become routine Heartbeat goes fast/ Palpitations.... Tingling in Tummy , confusion , indecision , and I go blank Brood a lot / Overthinking with present n future situations. I feel like I'm unable to do tasks although ultimately I do it but takes a heavy toll.. I feel less energy n fatigued. Your free consultation is very precious and I would be greatful if you can advise the right course of action. Thank you :)
