Hey /fit/, I'm looking for a bit of advice. I'm bipolar and depressed as fuck most of the time so sometimes I don't eat anything at all during the day, let alone manage to cook for myself. I'm thinking if I go with "easy" food I can perhaps do it however. I'm 5'7", 117 lbs and female, so my TDEE is supposedly some 1630.

I'd be looking at a rich yoghurt in the morning, an apple, a banana and then a pizza for lunch. I can eat craploads cause no matter what I'll be as hungry as before after 3-6 hours, so dinner would be a medium sized Burger King menu. That'd altogether make 2.6k, possibly 2.8k calories. Then I'll possibly need a midnight snack cause I'll likely be hungry again, so that's maybe a sandwich or some vegetables or so, totalling some 3k daily. I know I can eat this much cause I already did several times. That's nearly twice of my maintenance intake, and I'm aware Burger King food is not the healthiest thing to do to myself, but I've tried hundreds of times to cook for myself and depressions keep nailing me to the floor and it all goes to shit.

Would this be a real shitty idea or can I maybe keep at it for some 10-15 weeks, assuming I'd gain 2 pounds a week?

I've been the same weight since 16, that's been 8 years ago and I just want out of this hellish circle of gaining maybe 2 pound just to lose it again immediately.
