Psychosis or severe anxiety over night?

It doesn't effect me now but about 4 years ago when I was 14 I woke up one morning thinking I died in my sleep and I was in hell. I had no prior anxiety issues but I did have a problem with depression on and off for years. I have never been so terrified, I thought at any moment everybody was going to turn into demons and start attacking me. I wanted to be taken to a mental institution but I was scared to tell anybody because I thought they were demons. It felt like I was in a different world to the point I hated leaving my house just because everything felt so freaky and unreal, I can't even describe it. That feeling didnt go away for years. I had a hard time sleeping because I would start having violent images and random voices and laughs flashing through my mind. I had really vivid dreams or nightmares every night and I couldn't ever figure out if I was dreaming, in my dreams and in reality for months. I also developed a fear of leaves for awhile because I was in the woods and I realized they where everywhere and I had a panic attack (my first one) and if I thought about leaves for to long it would happen again. After a month I told my twin brother and he convinced me it was anxiety issue. And I just accepted that. But now I'm starting to think it was psychosis now I learn about it.

Sounds like anxiety, I'm thinking you're just under a lot of stress.
If it were psychosis, you wouldn't be questioning if it be psychosis or anxiety. You would just act out on how you feel. Also how you mentioned that you wanted to be admitted to mental institution kinda says you're sane. A crazy person wouldn't think it'd be necessary, since they'd believe what their mind is telling them is true.
