If I make a promise, I usually try to keep my word. The only time the promise really stops for me is if that person does something mean or horrible. Like, how I ended up losing my previous hero. Before I turned to visual kei, we were pretty close as far as the whole hero thing went I guess. I had spilled my heart out to him. I made a promise that he would be my hero no matter what. Then one day, after I got into visual kei and had my twitter profile set up for it, I posted on his recent update. He went on one of his favoriting sprees like he sometimes does. Mind you, he has ALWAYS favorited my tweets. Yet, this time... he skipped over my tweet like I didn't matter. I know damn well he didn't just miss it either. He never does that to me. Well, this actually broke my heart to pieces. I cried for two fucking days. I was just that devastated. I ended up changing my twitter name, deleting everything I had said to him and everything. I just couldn't deal with it.
However, any other time, I am a strong promise keeper. I don't like breaking promises to people. That's why when I tell them I do something, I don't actually make promises I can't keep either. It's really hard because if I become emotionally attached to said person as well, I end up becoming absolutely devastated when they leave me stranded or stab me in the back. I actually made this promise to my hero that I was going to be strong and do my best to improve my anxiety, or well... eventually I will tell him this. It will make it easier for me because it will help me in the long run.
Sorry for getting kind of rambly there. ^^;
