cardiac

i got a text today from a girl in my support group. she asked for support because her heart had gone out!! she figured it was from purging!! every time my chest hurts from purging i just push it aside cuz nothing bad is happening. what if that happens to me? if my heart gives out will i just push it aside as well? i feel like this is ultimately going to kill me. like there is no way to get rid of ED. im stuck with it forever. its really scary.
