Gotta admire your guts in talking about it, both of you. :)
I was put on antidepressants in 2014. They didn't help, so I went off them in 2017. Turns out I was never depressed, instead I have C-PTSD. Through the meds and an unconscious habit of emotional eating picked up from my mother (I don't blame her for it) I think I gained 30kg/65lb, peaking at 100kg/220lb in early 2018. I'm 5'6" so realistically that's moderately chubby. Hurts a little to say.
Since then, I've stopped emotional eating (substituted by ramping up the coffee and escapist hobbies even further) and started restricting most of the time. Little/no exercise as I have gradually worsening chronic fatigue. Like this, I've been able to lose 1kg/2lb a month.
Currently 90kg, would be content at maintaining 80kg/175lb. I'll be moving into my own place (converted caravan) soon, so I'll be handling my own meals - the plan being mostly fruit, water and lots of coffee, as I don't/won't have the energy to make/cook much. Sorry that was a bit of a ramble. I've never spoken about it.
I'm 24 and sure, I'll be dead by 30, but I want to spend my last years finally being the person I want to be. If that means a bit of self-abuse to accomplish one facet of that person, so be it.
