It seems like you have a nice breakfast of cooked oats most mornings. Does that fill you up? It's a fairly carb heavy breakfast and a LARGE amount of oats. I might consider having half cup dry oats instead and adding a bit more protein to it. Perhaps a tablespoon of peanut or nut butter or cooking them with soy milk instead of water.

I also think the times of your meals might be to blame. You usually have a very large breakfast and don't eat much more throughout the day.

I'd suggest planning out your food the night before to focus on some more balanced meals and snacks. Thursday your dairy looks beautiful. A little high on fat, but fairly balanced meals

I like to snack on fruit and add in peanut butter wherever I can. You can look at my diary for the week. I'm not perfect but I'm not starving throughout the day.

I don't think your protein is super low, or anything. It looks good to me since I truly believe we don't need nearly as much protein as the government (and meat industry) would have you think.

So... to recap, try to plan out your meals for the next few days and eat every few hours and journal how you're feeling (tired, achy, etc...)

I hope this helps and you feel better soon!

You might be anemic. I became anemic when I first went vegan. I can't see your diary, so I don't know how much iron that you're getting, but getting enough of it is pretty difficult without animal products.
