I Have Been Terrified Of Anxiety And Feeling Depression

I have anxiety and depression. I have no health insurance or a job or any way to get health insurance, that I know of. I used to be able to do everything, go to a movie, hang with the family, normal stuff. Now I can't go for a ride in a car without feeling anxious. I need it to be gone soon. I feel like this is going to ruin me. I'm already so mentally exhausted. It's been 2 weeks since I had a random panic attack *which are rare for me* and ever since then I have been terrified of having another. So that's what I think brought all this anxiety on. Ok so I haven't had an attack, but still have the anxiety....now I am terrified of the anxiety. I don't want to feel it anymore and am stuck. I think about it constantly, nothing will take my mind off it. I'm taking St. John's Wort *started yesterday* and Stresstabs. Can you tell me anything that might help me? I'm so sad every day I just cry now. That's all I do.
