Which Homeopathic remedy for Panic Attacks

Hi all, I'm a 31 year old male that suffers panic attacks and seeking your help in finding out what homeopathic remedy I should be taking to help eleminate this nasty problem. One summer day in 2006 while driving on the freeway my heart started racing little by little while both my hands were along with my lips were going numb 10 minutes later I had to pull over on the shoulder of the raod and got out of the car thinking that I was having a heart attack. By then I had lost control of my hands and mouth. I think it was because my heart was beating so fast and hard that it had stripped the blood away from my limbs. My girlfriend at the time who was with me got on the phone and dialed 911 cause we both thought I was having a heart problem. I thought I was going to die no questions asked, it was that bad. about 10-15 minutes later I started calming down little by little but the numbness and loss of control in my hands and mouth or lips was still there but a little less. I managed to take the phone from her and told the emergency person on the phone that I was feeling better trying to avoid thousands of dollars for an ambulance coming out to get me. I told them I would get to a near by hospital by myself which i never did. I just wanted to get home and lay down. Since then I've been getting these panic attacks every now and then while driving on the freeway or even being a passenger in a car going on a freeway. I've also been avoiding flying in fear that it will happen on an airplane and because of that have not seen my family in over 7 years. I'm not here to be judged so please do not. I will not lie to you, before these panic attacks I have been using ecstacy (the street drug) and have been using it about every weekend or so for the past 3 years before having my first panic attack. Of course I stopped using the drug right after my first panic attack and never touched it since 07/2006 I also quit smoking a year ago and never drink. I'm trying to keep a healthy life style including what I eat in hopes to make my body happy and rid it of these panic attacks. If I were to take a educated guess then I would say my panic attacks came about from my previous drug use perhaps from damage that I have done to my nervious system or brain. So unlike a lot of others out there who are clueless as of why they get panic attacks, If I'm right then I brought upon myself and regret it everyday I live. I have seen a psychiatrist once and back them my blood pressure was high but she just told me to monitor and lower my pressure and I did other than that having to health insurance and not wanting to be prescribed anti-depressant medication I never went to see an actual doctor. Later on I learned from a ex-girlfriend who studied Homeopathy that some Homeopathic remedies might help. She suggested I take Sulphur 200C and only one dose for now. Since I haven't spoken to her face to face and never done this before myself wanted to ask some of you kind folks if you have any suggestions of your own and if I should take this Sulphur 200. I'm also open to any other suggestions at this point. Your help is greatly appreciated. Thank you!
