I am one of the most anxious, neurotic individuals one will meet. Whilst I don't have any breathing or panic attacks quite like that, thankfully, my heart constantly pounds in fear at the most simple of tasks. For instance, I'm kind of sick today. So I decided to call in tommorow for work. But I procrastinated on it for a bit, and as I waited for my boss to answer, I was very anxious. Yet everything turned out all right, as it tends to.
My reason for anxiety is usually in regards to talking to other people. I always think they're going to yell at me if I even slightly object or break a status quo. People judging me is a fear I've had instilled in childhood, by my parents, who were highly judgemental. Even posting here and seeing others' reactions gives me paranoia, which is part of why I tend not to return to threads. I'm afraid someone's going to say something bad if I was particularly truthful. And same thing if I am conversing with others via private or visitor message. I am very avoidant and afraid of seeing their responses, particularly if I decide to reveal my true self rather than speak mindlessly. Luckily, since I've started taking my medication, my anxiety levels have decreased by a lot. Though my heart still pounds and I feel horrible, it's a lot easier to push that aside and do things rather than run away and be avoidant. Though it's still difficult in general.
But I am also neurotic about time waste, not doing things at the right time, and a person I depend on randomly dying out of nowhere and leaving me all alone. If I'm not interacting with someone else and fearing them, I'm fearing what's going to happen to me in life. Time... the clock ticking away... it always eludes me. I don't want my short time in this world to be up. Nor do I want my loved ones' time taken away from them prematurely. My mind is just a very uneasy place, and I constantly have to force it to relax. It's... not a peaceful existence, mine. But it has its advantages. Because of my paranoia, I tend to use it in stories to make some villains who are ridiculously elaborate and thoughtful in their plots, patching up most holes that the heroes could beat them with and making things more interesting. In general, because I overthink everything and think that someone is scrutinizing me constantly with a microscope, I can avoid a lot of plot holes.
