I've always had issues with intense anxiety and depression, but never anything like this. I've always thought of things a weird way. It started when I was really little, and went to church with my grandpa. I would ask my parents if they knew heaven was real, and I would be filled with a very intense feeling of dread. I remember very clearly my dad once saying, "You're starting to scare ME now..." After I was a little older I would ask my mom questions like, "Why is pain uncomfortable but pleasure feels good? If it all happens in your brain, why do you have to see it as uncomfortable?", to which she would respond, "What do you mean? Because it is! That's a dumb question." I would start asking questions about how we could know what's real when your perceptions are processed by your brain, they're subjective to however your brain puts whatever input together. I would tell her that people can never truly know each other, because they can't know their thoughts or experiences, they can just describe them, but it never shows them the whole picture. Some things just can't be explained to another person. I was never good at explaining myself, so after a lot of confusion, I stopped talking to people about it. About 6 years passed and I started thinking more deeply as I got into high school. This led to very dreadful thoughts, and lots of panic attacks. I started noticing how strange everything was, stick with me here... this is difficult to explain, but I think I can describe the feeling a bit. It's like... I'll just be at a friends house or something, and I'll notice how strange it is that things exist, let alone exist as they do. Everything starts to seem more like a movie. I can feel myself behind my face looking out through my eyes. I'll look down at my hands and legs and they just look strange... alien to me. It feels strange to have my arms extending out so far, I have to try to do natural things. Walking is more deliberate, I have to purposefully put one foot in front of the other. I have to think about breathing and blinking. I'll look at my friend and wonder why it is I'm perceiving my thoughts, instead of his. It seems so impossible that the same molecules that make up a rock can produce consciousness when arranged a certain way. So this leads to me believing I may the only person who ACTUALLY exists. I understand that logically, it shouldn't matter because your experience is the same regardless, but it's still bring up a very sick, sad and anxious feeling. I can physically feel the feeling in my stomach and chest. I don't know why I care so much. I try to help people out a lot, sometimes too much to the point that it can harm me (and a lot of people owe me money). Maybe this is why I care so much? I don't think so though. I don't notice that strangeness ALL the time, but I can remember the feeling, and it hits me randomly. It seems to be much more frequent. It usually only lasts around 20 minutes to a few hours, but on one occasion, it lasted for almost a week. Does anybody else understand this strangeness I'm describing? Can you explain it better?
