Another mind

I feel like I have to focus on one thing or I'm going to go crazy. Like I always feel like whatever I'm doing I can't feel anything about the situation. Like I will be talking to a girl I like and we will be flirting and shit. Like I feel happy but for some reason i think I'm not. I always feel like there is something in my life that I need but don't have. Something I can really enjoy. Also I feel like I stop to much to step back and look at life. Like I feel I'm just going through the motions. But I really know that I feel everything. It just bothers me to no end.
