Ah, I went through this a long time ago. Socializing is a really tedious thing but being alone is difficult for many. Fun stuff right? To be honest, there is no answer to it. Even if I devised a plan for you, it wouldn't mean much in the end.
>>2 I don't think Asuna desires solitude for that reason. That human beings are cruel and what not. I think it is more fundamental than that. A natural repulsion, a loner type attitude. Like standing around in a group of talkative people and just thinking how boring it is.
Balance is a great suggestion but I'll tell you this right now. After a long time of studying myself and others, I finally reached complete balance. It's not easy at all. It's actually much more difficult than picking a side. A true balance requires an indifferent attitude and the wisdom as well as strength to use it. The desire for company, for friends, can be overpowering and is almost always reflexive. In order to suppress it, you have to simply look at it as if you don't need people. You have to lose your interest in people entirely. In order to suppress the other side, the loner-ism, you have to reverse the thinking and believe in people as much as you can. You have to find human beings interesting. In order to balance them, you must embrace them both equally, allowing them to overlap as they desire. If you attempt to maintain a half ass balance and delude yourself, you will torture yourself more and more.
As for not knowing what to say when talking, that just means you are bad at conversation, social interaction. You can remedy that easily and the social you/loner you can only interfere in the process.
Perhaps your distaste with social formalities or people in general is just because you are having difficulty maintaining a conversation?
