(Anorexia warning⚠️)what is happening to me??

So I know this is a heavy topic to talk about, but I don’t really have anyone to talk to about it. I am diagnosed medically and I have both bulimia nerviosa and anorexia. The past few days I’ve stopped purging and only have been starving myself. Today I was extremely tired I have never felt so tired before and I felt weak. I talked slow and just didn’t have much energy. I finally gave into eating today and now my body just hates the fact that there’s food In my system and it’s almost as if my body is restricting me from eating too?? I’m sorry if this post seems annoying and like I’m totally saying it’s okay to do it IM NOT! I just don’t have anyone to talk about it with and I just don’t know what to do anymore. One second I want to be healthy but the other half of me doesn’t want to let go of the fact that I can purge and starve myself.

UPDATE: I’m feeling extremely lightheaded almost as if I’m high and I can’t function right I feel like I’m going to pass out
