I have being reading some posts of "unreality" recently. However, my thought pattern seem similiar in some ways, but in other very different. Let me give an example...
While sitting by a camp fire, looking over at others and thinking,... "Why, why do they want to keep living. How has life convinced them it must be lived. Do they just choose to ignore that all they are is just a bunch of nerves, a blood and oxygen/bioelectrical machine. It all seems so pointless, so meaningless. Just a perpetual cycle of life,...why is it anyone craves to keep doing anything?...etc etc."
The thoughts seem to come in waves overpowering with questions. Usually right when I'm enjoying something. Like when recently meeting a girl. I remember thinking, "wow, she has beautiful eyes...why, why do you care about her eyes. They are just a bunch of cells, light reflecting off of them. That's just a rush of endorphins you're "feeling" ...so pointless... what is your happiness but just merely bio-energy flows in your body. Why do you care about it at all. All the feeling you have for this girl are merely just wishes of your body to procreate,... why did you ever think this is so important, why do anyone?"
I just want to say, "shutup, I like her eyes okay!" I relate it to having a really synical friend there at all times. And it can be very strong, and make it very difficult to enjoy the situation, because it belittle the feeling of enjoyment at the root.
...Just a quick bio of me...I'm 26, exercise regulary, run, yoga. I meditate. I take Zoloft. I see a pyschologist. So, I take a lot of care to treat my emotional/physical well-being. I have a great job. I'm respected for my talents. I have a lot to be thankful for and just wish I could convince my brain of that

Well, thanks for listening.
