Hi Nikki ,
Thanks for consulting us.
As you have said these are classical symptoms of PANIC ATTACKS. This occurs due to stress/ anxiety
which alter the amount of NEUROTRANSMITTER(Chemicals inside brain & nerve).
You should start taking,
1. PAROXETIN - 1st choice in Panic attack.
Mouth Dissolving SOS sublingually during the attack.
Along with this you can get help from meditation
and yoga which will lower your anxiety.
Consult a good psychiatrist
Best of Luck.
