Hi, I read your query and can understand the distress that you seem to be having due to your symptoms. From what you have mentioned, it seems that you are having panic attacks. Panic attacks are sudden heightening if anxiety associated with restlessness, tremors, increased heart rate, sweating and feeling that one might die, or have heart attack or go crazy. Recurrent panic attacks can occur as part of panic disorder which can be present with or without other anxiety disorders or depression. I would suggest that you seek a psychiatric consultation for detailed evaluation of your symptoms and proper management. Had I been your psychiatrist, i would have ordered few investigations initially including ECG, complete blood counts and thyroid profile to rule out any underlying medical condition. Treatment with one of the selective serotonin reuptake inhibitors (SSRI) like escitalopram or paroxetine would be effective. Short term course of benzodiazepines can be given initially for controlling anxiety as the SSRIs take 10-15 days to show its effect. In addition, you can start exercising daily which will help you relax. Hope this information was helpful. Best wishes.
