Ales, I'm so very sorry you're going through this.
I had disabling panic attacks throughout my 20s, some in my 30s. They gradually tapered off and now I have not had one for many years. Occasionally, the signal of the familiar symptoms (in my case, it was always heralded by dizziness and chest pain--and especially shortness of breath. Gasping inability to feel I was taking in enough oxygen. I also had them driving, and in my 20s, reacted with a degree of near-agorophobia for some time).
I still to this day always carry 5 mg. of diazepam, because I know if I take it immediately, it will nip it in the bud and never become a full-blown attack. (It's always hard to remember when you're in the grip of one, but they are self-limited...they come, peak, and do pass.) My memories of those are so powerful that I am very happy to take it when I need it. Now, usually, only once or twice a year.
I can't say I know what would be right for you, in terms of medication or hospitalization, but I can share that for me, having the Rx on hand was very important in giving me a sense of safety, a way to manage an acute attack. It gave me a plan and a physical take-the-edge-off-terror that I just wasn't able to achieve rationally. I always worry about dependency because I was such an addicted smoker and always alarmed by dependency...but it has never happened. I dislike taking anything that affects the CNS (central nervous system) and because taking too much would trigger apnea, which is even more scary, I have a built-in resistance to taking it unless absolutely needed.
I'm talking about the benzodiazepine or similar anti-anxiety medication, above. For many people who have panic disorder, they also have depression. I definitely was clinicially depressed as well as ripped up by panic attacks...they overlapped, so I thought of it as "depxiety."
Fortunately for me, the SSRIs tend to reduce BOTH anxiety and depression. I am no longer on them now, but for a decade or two, antidepressants (various SSRIs) was a godsend. I had several intervals of several years when I did not take them. But when I needed the help, I needed it, and was grateful they were there. While I did therapy too. It's been years now with no need for Rx--but I'm 60. My alternate methods do work pretty well. (SAD light, exercise--when I do it, which I haven't been!--and lots of tea.) And just getting older helps too. When my anxiety was at its worst I cut caffeine out.
Another tip that helped me was loosely closing a small paper bag around my nose and mouth and breathing into that until my symptoms subsided.
Let us know how it's going and what you decided.
(I did not like Prozac. Effexor was helpful to me, and the last time I took them, it was Cymbalta. Very helpful.)
