yes, its possible. its possible you alreday have an eating disorder and tried a more dangerouse one. if you want to keep purging or have strong feelings to, its possible your bulimic, however if its just soemthing you did once but you still strongly feel like you need to starve yourself or not eat to losoeweight or get control over your body, then you have a different eating disordser, talk to a doctor about it and talk to people about your problems rather than bottling them up inside and doing drastic things to release your pain
It's not only a physical problem, it's mental.. You need help, or you could end up becoming seriously ill.. not only can you die from lack of nutrition, your immune system is lowered and you will become more susceptible to sickness.. Expect your family & friends to be concerned.. You're obviously are realising that you do need help.. Seek it...
You could become bulimic. I would advise you talk to you're doctor though, if you're thinking of doing it again. No one wants to see you go through that and no one wants to loose you. I dont know you, but every one is important. Please dont do it. it will kill you.
Get help. Talk to someone you trust, because it could progress into something worse.
