Sobriety Online

Yesterday I decided to get help for a "cocaine problem" that I'm not even sure is a problem. Anyway 10 hours later and still high no one could help. I couldn't get help or even someone to point me in the write direction for help. At a rehab center they basically said we don't admit on the weekends. Mind you I'm kinda freaking out. I called every hotline I could find and no one helped. I got so pissed iff thar there wasn't 1 person to help me, listen to me, comfort me (still high). So nothing until Monday because nobody uses drugs on Saturday or Sunday. Where do I go from here? How do I know if I need help? Anyone?
