Starving myself to lose weight?

I’m posting anonymously so I won’t reply to comments but here’s the run down. I’m just over 9 stone and 5ft 2. I want to lose weight but also I’m in a bad place mentally so I also want to “punish” myself in a sense by not allowing myself to eat because I don’t deserve too. Sometimes I can’t help myself though because I’m a bit of a comfort eater. Before anyone tells me to speak to a doctor i’m already under a mental health specialist.

How much weight do you think I could lose by eating one day then not eating for two days and then back to one day and off for two days again? I don’t know how long I plan on doing it for. I’ve binged today and I won’t allow myself to eat for a couple and I’ll see how I get on and weigh myself daily.
