Thinking I got triggered? (Trigger Warning)

Last Thursday night, I was online and I stumbled upon a message board having to do with anorexia. I spent a good part of the night reading posts on there. After doing so, it all got stuck in my head. It mixed with the fact I self-harm. I haven't eaten anything since Friday night. I'm on all liquid diet, that master cleanse one. I'm 26 and I'd put myself in the little extra baggage category, so I can stand to lose some weight. It just feels like its easy now, that I want to do this until I'm dangerously thin and maybe further. I'm not even sure I can stop already, something inside won't let me.A few times in the past year I've told myself I'm never eating again too. What have I done

I'm in a similar place right now. I haven't been on the SH forum as it hasn't been such an issue lately but am a member of the Bipolar one.
Any advice i could give would feel really hypocritical because i wouldn't be following it myself.
Do you have any other interests that have got you through depression in the past? (not insinuating that you are feeling that way) just try not to make this the only thing in your life. For me it's art so I'm allowing myself time to draw just so i don't lose what's left of my mind
