If I can't stop thinking about killing myself during a panic attack or think that I'm dying, does that mean I actually want to kill myself unconsciously or is it something else?

There is a difference between thinking about suicide and intending on suicide. If you experience suicidal thought without any intent that doesn't have to mean you are unconsciously suicidal. Of course, if you do feel bouts of intent (planning, gathering supplies) I would talk with someone, but otherwise I think you're not a danger to yourself at the moment. Do keep an eye out though, and let those who are supportive of you know that you're worried.

This is just because of the stress due to which you're panicking. It's nothing like you want to die, your life is really precious my friend. Dying is never a solution and your brain won't make you go that way. So I feel it's just a feeling because of the panic attack and nothing else. Just calm down! You don't have to kill yourself or anything, keep your mind calm, listen to some soothing music, do the activity you love to do the most, or dance maybe, don't think of future outcomes, your health is worth more than the work load or stress causing factors.

It means you are afraid... well your brain believes it anyway and it is trying to escape the situation. I know because i have panic disorder. Meditation, tea and therapy will help this go away in time

Yes, I've had experiences when I thought that I'd die from what turned out to be an anxiety or panic attack. First, the reason why I think that I'm going to die is because my brain is convinced that the 'symptoms' I have are most definitely a stroke or heart attack, when it really is nothing but the effects of anxiety. If you first accept the fact that you are suffering from anxiety, and not a chronic illness or disease, that may help. Next, of course, is to overcome your anxiety. I suggest consulting your primary doctor or perhaps a therapist. Maintaining a natural, healthy diet is key to combating depression and anxiety, and I've read that waking up early (as opposed to 10 or 11) helps out too. Try meditation, exercise, and stretching; a lot of people recommend this :) Hope this helps a little
