If you are in the midst of recovering from anorexia, and then you purge . would that make things worse ?

would that set my brain back to beginning . because i have been feeling a lot more normal the past 2 days after all of my days of starving and feeling so incredibly weak . and purging and spitting out food . but after yesterday i ate a lot of food (which might not be a lot to other people but it is to me) and i know purging ois HORRIBLE for you . but i do it and would that set me back to the beginning ? because i do NOT want to be back at the beginning at all :(
