Although its a good goal, I think going from one meal and one snack to a full three meals with two snacks is pretty drastic to do! It might be reasonable to try working up to that goal more gradually over the next couple weeks. Then have a solid week or two with your goal met by the time you see t again.
If you have a hard time eating early in the morning you could try having a fruit smoothie, boost, ensure, or some other liquid nutritional breakfast. If thats too much in the beginning you could start out with a glass of milk, chocolate milk, soy milk, fruit juice, just something to start you getting in the habit of having something in the morning.

You can set alarms on your cell phone or computer to remind you its time to eat if you don't get cued by a hungry feeling. For snacks especially it might help to have things that are easy to grab like protein bars, fruit, crackers and peanut butter, all the places you spend the most time. Bedroom, living room, desk at work, backpack at school, in the car, etc. Try different schedules for eating too. You could have two snacks after lunch and a late dinner, or a bedtime snack, or any schedule that works better for you. It might also help to invite friends or family members to share meals with you. That way even if you forget, they'll remember. And hopefully, even if you don't really feel like eating, you will want to see your friend.

It will be difficult, but I hope it will start getting easier soon. Keep trying. You're being very brave.
