I am fourteen please help me I feel like I'm about to die..?

I am bulimic (just the purging) and have been for about a year and I'm also anorexic and have been for two years. Okay so I was already feeling lightheaded so I ate something and then I purged it and a shitload of blood came out and that usually doesn't happen and I feel so lightheaded now and I purged over 30 minutes ago but my throat still burns so bad that I almost scream when I try to talk but if I scream then it will excruciating. Whenever I move my head up or down a whole bunch of brown spots cloud my vision for like ten seconds. My stomach hurts and I feel so dizzy I can't walk. I was about to call my parents but for some reason I cannot remember my moms cellphone number, I don't know why, probably because I am so dizzy, I can't remember which number in my headnis my best friend's, sister's, or mom's. My parets went out to dinner with friends and won't be back till like midnight, it's 10:30 now. Should I wait and see if this passes or call 911? I all the sudden feel tired but I'm afraid if I go to sleep I will die. It's a very sudden fatigue. SHOULD I CALL 911, IT'S THE ONLY NUMBER I CAN REMEMBER? Help me I'm begging. Thanks.
