do u feel nervous about your life anyway?

Being nervous is normal, but it is a cause of worry if it causes you to be rude to others. Being rude to others is not nice nor will it make your life any easier. It's much better to maintains good relationships with other people. Nervousness is usually brought about by something that is going to happen which makes you anxious. It could be a good or bad thing. You didn't say what really makes you nervous, but it cuold be something you are anticipating. If there is absolutely nothing that should make you nervous yet you feel it anyway, maybe, you are in such a tensed situation and I suggest that you take some time by yourself, relax, think of other good things in life, and don't devote yourself to the useless habit of worrying. Hope this helps you...
