Thanks a lot, I know what should I do. Sometimes I think one's look is not a big problem, but I must change my mind, human are optic animals.

appearance is not important in our relations .The most important things are your thoughts and your heart ..our prophet Mohammad says God doesn't look at  our appearance but our deeds

I don't think one MUST be pretty or handsome, but,for sure, we need to be wearing neat and tidy clothes,we should have haircut( not a haystack on your head), to have shower as often as we need to...These things are very important when we want to get a good impression about yourself, that's what I'm certain about. Since we are humans, we should care a little about it. If I see a good-looking person who smells not good enough, I can't accept that he or she are good-looking. And If they say some stupid phrase, it's even worse than their smell...
