I can’t eat

I don’t really know why but recently I’ve noticed that I don’t eat as much as I used to, whenever I was having an especially bad day I’d usually eat more then normal. I was recently put on some medication (2 weeks ago) so I thought maybe that could be the reason but I noticed that I started eating less over a month ago so that can’t be it. I used to weigh 114lbs and now I’m down to 105lbs and people keep commenting on my weight but it makes me really uncomfortable. It’s gotten to the point where I had to force myself to eat today and I managed to get down one egg, half a bowl of soup and 2 scoops of ice cream. I feel hungry but I don’t want to eat and I kind of like the feeling of an empty stomach. I’m really hoping that the weight I lost was all water weight but I’m not sure, I’ve been super thirsty lately and have to pee more often. I have clinically diagnosed depression (like most everyone) so it’s not like I have a decreased appetite because of new depression or something similar. It super confusing because I’m supposed to be happy, everything is going well, getting better and I’m still a kid so I need to eat to grow a bit more and you’d think I’d have a bigger appetite because of that. Eating just seems like a chore and I don’t want to do it. I don’t even know why I’m writing this, I’m going to attempt suicide tomorrow.
