Where can i get help in the UK for bulimia? ?

i was 16 when i discovered bulimia - at the time, it felt like an ideal solution. i could eat exactly what i wanted, yet relieve the guilty after-feeling by 'disposing' of extra food that i was convinced would make me fat. for me, bulimia isn't so much all about being thin although that is certainly a drive behind it. for me, bulimia is about being in control. when the rest of your world is falling apart around you and you can't change a thing, bulimia helps me and for that reason, i often think of it as a 'friend'. sad, i know..a disease comforts me. but it does... when i would be having problems with friends or at home or just generally feeling down, i'd resort to bulimia. i could change myself, i could be whoever i wanted to be as long as i lost weight and changed my appearance. after i lost a little more than 22 lbs in 2 months people started to comment on my weight. some people would be shocked as in 'whoa..you've lost so much weight..you look a bit unhealthy,' while other people were complimentary telling me how slim and nice i looked. these comments only encouraged me - the bad comments convinced me that people were jealous and wanted to look like me and the good comments made me feel that what i was doing was right and was having the desirable effects. i would start to look around me and think my 5 ft 5 friend who weighs about 130 lbs was fat, obese even. i would look at her in disgust as she ate a sandwich for lunch, convinced that she'd let herself go. at school i would eat nothing. often at home i would get out of eating too and those days i felt in control and happy, especially when i was getting a bit bullied at school. but some days when i got home i'd go crazy, eating every single thing i could find in the cupboard. i'd feel sick afterwards, as if i wanted to die and would throw it all back up, telling myself i was sick and disgusting and i didn't deserve to eat. then i'd tell myself that no wonder people didnt like me, i was a disgrace. then i'd go and cut myself - each ugly scar that remains on my arm reminds me of a different day when i'd just lost control. this story saddens me even now because even i can see how wrong i was...and i did get better. but i fear its coming back now and my depression is even worse. i dont want this to spiral back into the full-blown bulimia i had managed to recover from before. a bulimic can never truly recover i suppose but i want help this time. i dont want to be the person i was back then. i got dangerously thin and was so unhappy so if anyone knows of anywhere where i can get help or has any recovery stories of their own, please let me know :) thank you for your time. x
