My anxiety has come back after slowly getting back to my normal self. I have started getting negative thoughts in my head, constantly fear of dying and scared that something bad will happen to me. The 'what ifs' keep running through my mind. I am 19 years old and have my whole life ahead of me as people keep telling me. But how can I live my life when I'm always having these fearful thoughts 
ABSOLUTE NIGHTMARE!!!
Angie, I am so sorry you are having these feelings. With everything that's we see on the news, it's no wonder people are living in fear. However, that is no way to live. Most of our fears never come true; therefore, we worry for nothing. Please see a therapists. Try to replace thoughts of fear with somethiing pleasant...like nothing has happened to me yet...I should not worry about what might happen. I wil not die before my time, which I do not know and can't do anything about so I must not concern myself with that thought. praying for you.
You need to see a psychiatrist NOW and get a anti-anxiety/depression drug in order to alleviate those feelings now. Don't wait. Anti-anxiety medication works immediately and you need relief right now or you may do some thing that you can not recover from. A lot of hearts depend on what you do. I lost my brother. Don't let any one lose you. Especially not yourself. You can work out all the why's and what for's later.
Have you seen your GP? He's the one who can refer you to the right professionals. Before you go write down your feelings /symptoms and how they are affecting you.
Best wishes
