Hello, My name is Brittnee. For the past 5 days I have woken up with nausea, but I haven't thrown up yet. I've been weak and can barley get myself to get up to go to the bathroom, completely exhausted, with no energy. I'm 17, and feeling like this scares me alot. Every time I stand up I get dizzy. I can barley keep my eyes open, but I am not running a fever. What could possibly be wrong? Please answer soon, I'm getting really scared and I don't have insurance so I can not go to a hospital.. and yes, I am sexually active. I always get asked this question, please help.
