Hi,
call it however you want to, but if you identify it as a problem, you should start putting an end to it before it gets worse. Talk about it with your therapist and she/he will give you some tips so that you can learn other ways to feel better. The relief you feel by purging is just temporary, it's not the solution to anything. It's normal not knowing the appropiate tools to cope with certain feelings, but those tools can be learnt, I can tell. Have a chat with your therapist and ask him/her to teach you how to deal with your feelings or emotions
Hugs
