Yes, I don't think the OP will listen. Either they are genuinely suffering from mental illness, perhaps using this forum as a cry for help, or perhaps they are internet trolling, for cheap thrills.
I have a feeling there are multiple posts from the OP, in relation to fasting possibly under diff user names.
I always knew curezone would eventually attract posts like this. I really am concerned for the OP.
Saying they will do anything to achieve that weight is honestly going to kill them. The body cannot sustain function under those conditions. This is far far worse then self harm. This is severe abuse that will lead to death.
