I’m not diagnosed with any sort of anxiety or have super regular encounters but when I have panic attacks or feel one coming on it’s either being overwhelmed or depersonalization. 
When I’m alone and the weather is strange, mostly at night or when I wake up and the sky is heavy I feel like I’m dreaming or nothings real or everything is significant or has some creepy meaning. I have no idea how to help myself when I start having those feelings. Does anyone know any methods dealing with this kind of panic?
