anxiety and serious panic attacks

Hi. I've had serious anxiety and panic attacks and depression since I was a teenager. I would just love be a totally calm person at all times.

A big problem I have is always trying to say things fast in response to people talking to me. It's like if I don't respond fast, they might not like me.

Please I need a total cure for this. Please try to recommend a natural remedy/cure that'll make me completely calm and in control at all times. I just believe that there has to be something out there for me. I desire to be able to speak slowly and calmly, and not fast and nervous always trying to prove myself to people.

I need ur help please. I also walk vey fast, and it's not attractive, believe me. I'm a 23-yr old female, just in case u were wondering.

Thank you.

Jen
