Re-started Bulemia - headaches and my gums bleed

I was bulemic on and off for three years. It wasnt as much about my weight as it was about control of my life. About two months ago, my friends found out and helped me, temporarily, quit.

I thought I could do it by myself, and I tried and tried, and I fought every urge. But then about a week ago I started having problems again. My mom was nagging about my problems in school (I couldnt focus due to fighting the urges) and my dad was fighting with my brother. Soon, I found only myself at fault and began criticizing myself and finding faults.

I swore I'd stop, but I've started throwing up again. My parents knew I quit but they don't know I've restarted. I'm scared. I'm scared because I want to stop and I hate throwing up and I hate thinking I'm fat when I'm average for my weight. I'm scared that I won't be able to stop before it's too late.

I have symptoms from what I'm doing. I get horrid headaches and my gums bleed and my ears ring. I even got so malnourished one time that I fainted. I throw up 3-4 times a day... I'm just scared for my health and safety

I just dont know what to do anymore
