Welcome to HCM
We understand your concerns
I went through your problem description. I suggest you not to worry too much. I do not think that the incident is the outcome of panic attack
. But you did become anxious when you had the sudden sharp pain
in your left arm and numbness
. You managed to pull over, but you were so panicked that you sweat and felt breathless. Explains.
But, the first part needed to be investigated. You are a depression
patient and I don't know whether you are continuing the medication for it. Anyhow, it will be better if you get yourself investigated for the incident.
Hope this sheds light on the query. Available for further clarifications.
