Imagining the negative future
Is it normal for me to always imagine the future by visualizing a scene involving me and others with a pessimistic mindset when I'm alone? Every time I do this, I'll break out in tears and it's because I think about these stuff! I only do this when I feel lonely and I'll be staring into blank space with a scenario in my head. These scenarios are always against me and hurt me emotionally. So.. is this normal? Is anyone else like that? Or perhaps, is there a mental illness for this?
Thanks much.
