You are not the only one. And you know it. When the time comes you'll find someone special.
You say you are improving, that's good. Keep on trying to talk to people and be confident and optimistic. Get to know your friends well. Hang out with them and spend time with them. It's okay if you don't want to go to clubs. Go to movies or go out to eat something. There are other places and activities you can do besides drinking and clubbing. Like going to swimming, or a park. Interacting with people can help you find someone special. People won't leave you when they'll find out that you don't have many friends. People will leave you if something bad happens, you did something wrong or when these people are not interested to be your friends(these people are usually attention seekers, they'll come to you when they are lonely but will leave you when they don't need you. If your friend who left you is like this, forget about this one and look for some other friends). Try to be friends with everyone. Add them in your contacts. Like you can exchange phone numbers with them or if you are in a social networking site like facebook you can add them as your friends. Message them every now and then, share photos and posts.. You don't have to impress them. Just be yourself and be a good friend. Listen to them when they talk, help them when they need help or ask for help, congratulate them when they win something or when they tell you a good news.In short be nice and polite. Don't worry too much. Yes it's true that sometimes we are not aware of what is going around us and the people around us and we might say or do something wrong without intending to hurt them. In that case when you realize your mistake, give them your sincerest apology.
Take care.
