hi troy
it could be that if you don't have other friends or activities in your life, that you simply miss the good feelings you have when you are talking to her when she isn't available and that is what is causing this restlessness. you may also want to consider that you have deeper feelings for her. welcome to psych central. you will find we have several forums where you can post about your concerns and receive feedback from other members. you will get a lot of support here. again, welcome
