How to cope with severe anxiety and turn my life around?

So I have always been raised in a Christian household, but never actually believed or followed the Bible.

Well, I have been struggling with severe anxiety over death and dying, and getting health related illnesses.

So I have recently started going to church. I really need advice on what I can do to turn my life around?

I have also always struggled with anger. I'm in a bad place in life. I live with my boyfriend. No job, I had gotten kicked out of my moms and I just want to change my life for the better

I am 19 and about to start college. So that's one good thing!! But everything else is just falling apart.

Any advice at all would be great
