Keep going! You're on the right path and sometimes it takes a long walk before we feel like we've gotten anywhere.

And remember that although you think and believe that other people are looking at you unfavourably because they can see how shy and nervous you are, it may not be the case at all. In any case, some people find those traits attractive and you wouldn't be able to tell that by looking at them either. Some may be able to relate to you because of it and would want to be your friend (but may themselves be too shy to ask).
