I don't really eat much but it has less to do with depression and more with my past life and being busy all the time. I just got used to not eating much while being constantly on the go and it pretty much stuck with me over the years. Just quick bites and dash. Microwavable and instant meals really aren't the healthiest to live off of for years at a time though.
On the flip side, cooking does feel like a chore, it just feels like it takes too long. Probably cause I'm just not used to it. I do try to eat every day at least.
I drink plenty of water also.
