I'm experiencing anxiety since the past 3 days. Previously I never had an encounter with anxiety or panic attacks. I get irritated by every little things. I feel a constant pain in my head and fever. Also I feel increased heart rate and extreme sweating from palms and feet. I also have difficulty sleeping. During the panic attacks I feel like committing suicide as this seems the only option to ease out the pain. I couldn't consult a psychiatrist as none are available in my city (everyone out for diwali vacation). Can you suggest me some medications or give me some advice on what should I be doing. Most importantly why is this happening to me? I mean is this gonna be permanent or its due to some deficiency in my body (my calcium and vitamin d3 & d12 levels were very low last time I checked around 10 months ago)
