Is it anxiety or is it real?

So this post is kind of going to be all over the place because I’m going to try to explain myself but I’m not sure if you’ll understand because I myself don’t understand. I feel like the world is ending I feel like I’m dying. And it just feels very very very very real like it feels real. I’ve been struggling with anxiety for five years. My anxiety was really bad before I started working at 17 and when I would have a job my anxiety would be low I would still have a few anxiety and panic attacks. I haven’t worked since December and my anxiety has definitely gotten worse. I don’t think my anxiety has ever been this bad and it’s honestly terrifying like I wish there was a bigger word for terrifying because it’s beyond terrifying me. All day every day any little noise or sound terrifies me because I think it’s the world ending. Are used to be able to tell myself that everything is fine it’s just all in your head but now I can’t it doesn’t work anymore. I just don’t know what to do I don’t know if it’s real or not I don’t can’t tell anymore
