Opinions?(tw self harm mention)

Eating is becoming so hard for me?? The thought of it makes me really uncomfortable and nauseous I kinda feel guilty about it and selfish but I don’t know why- everyday I eat less and less and I didn’t realize till my mom asked me what I’ve eaten today I mean I did relapse recently and I haven’t gone a day without cutting- and my motivation hasn’t been the best could that have made me sick?
