Feeling Lost and Alone: Nostalgia for the Past

It really is just life. Your problems right now are mental and emotional problems... You're overthinking it, thinking there is some big meaning to every little thing, questioning your own position in your own life. This is happening because of stress, and it's not how you will always see things. I know because I've been there. You need help sorting out your stress. And make sure you're doing what you can to take care of your body. Sleep, food, water, air, sunlight, all these will effect how you see the world. Also, that stuff about repetition and insanity, that's not a real thing. You can safely ignore that. It's just a thing people say to sound deep. Who is or isn't "insane" doesn't really matter. What really matters is people getting their needs met, so make sure you're trying to meet yours. Good luck!
