do i have anxiety ?

I stay up almost every night because my mind decides to think of everything bad that could possibly happen to me, when i’m driving in the car i find myself thinking of my getting in a really bad wreck and possibly dying, this happens to me all the time and it is really starting to affect my sleep now. i don’t have issues speaking with people or speaking in pubic nor do i have trouble concentrating. i jus make myself scared of everything all the time. this is really a new thing for me and i don’t think any even caused it in particular. would you say i have anxiety ?
