Anyone else dealing with unjustified anxiety?

So, I'm dealing with lots of anxiety lately. About money, the future, hitting rock bottom, whatever. But the thing is, I'm not in a position to be anxious about these things. I have a decent paying job with an unlimited contract. I have an appartment, a loving gf, I'm healthy and even if shit hits the fan, my family would happily help me.

Still, I get like panic attacks when I think about some stuff. The fear of my car breaking down, for example, makes me feel like dying, despite being able to buy a new one without problems.

My anxiety feels misplaced. When I walk to my job (because even that's a luxury I have), I walk past homeless people sleeping on porches, I walk past addicts shooting up etc. and I think ti myself: 'they are so much worse off, What do I worry about?'.

Years ago I was trapped in a life of crime with very little perspective, and even then I didn't feel anxious. Now that I have monumentally changed my life around, I worry. It makes no sense to me.

Has anyone else felt this way before? Or ar you still having issues like this? How did/do you deal with it?
