keiruso,
your name sounds Japanese. Is it?
First of all, thanks for caring instead of judging.
I guess that ideally, we'd be happy and loving all the time. I think maybe one of the things that makes me a little different, is that I don't neccecarily fight the bad feelings. While I don't try to produce them, for example by listening to dark music, dark music fits the mood perfectly when I'm in it. It's basically like reading some of the more "depressive" psalms.
Sinful or not, I am simply not able to think happily and positively all the time. I ask God for forgiveness all the time though, for being the way I am, for not defying myself so to speak, for, well everything. If nothing else, I'm honest. Lying certainly doesn't help much during an anxiety attack, I find it much better to accept my dark thoughts and feelings, and Nine Inch Nails helps me do that, so the attack passes quicker.
Again, I don't know how much sense I'm making, as The Fear is riding me as I write.
When it comes to the way I think, well, I see so much beauty in Jesus, in people and all around, and I enjoy that, but still, people are crying everywhere, they're dying, my neighbor's wife perhaps just left him, this world is so full of death and darkness. I want to be a light in it, but I can't be happy all the time. Not even half of the time. I'm not trying to justify myself, but that's how it is.
Anyway, sometimes I think being like this is worth it, since I can (maybe two or three times a year) experience the opposite of anxitey; a sudden and profound sensation that everything is good and in harmony, peace. Also, I can feel such pleasure and peace when worshiping the Lord that I'm not sure the "normal" people get to feel, since they're normally "brighter" than me.
