I don't know why but it's been really hard to eat

I don't have any motivation to eat anymore, I eat less than a meal a day for the past month. Not telling people to give me attention. It's just really annoying feeling. I used to have cravings and stuff but now it's completely different. Plus now I get alot of low blood sugars now..
I am very sick right now because I took my medications on an empty stomach again and I feel like I'm going to get sick. I'm not suppose to take meds on an empty stomach but I have no motivation to eat, no interest in eating and no cravings. I just want ice water all the time
