Almost fainted - NEED HELP - am I underfeeding/dehydrated?

I'll make this quick, I was peeing and I almost fainted. The sound blacked out/visual whitened, and hands vibrating. I feel so bad after feeling happy about today...

Took a shower. Looked at my body and look like a holocaust survivor. I don't even want to guess my body fat percentage. :[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[ and the shower made my facial scars reappear/redder. :[[[[[[[[[[[[[ I am however 98lbs, but for 5'6.5'', that ain't much.

Mouth was dry. Afterwards, had broth again and helped somewhat. Drank a glass with it.

I want to know what kind of food/drink will help put fat/reserve into me. It seems like my body is still using my fat and just drinking juice and broth is not enough or maybe I'm not eating as much?. :[ Can I have almond milk or coconut?

Should I add a pinch of Sea Salt to my water and should I drink more water throughout thhe day?

Some info on my refeeding. I only drink around half a glass of juice with a cup of water in the morning. Broth is a small bowl/little over a cup with glass of water. I pee once a day but I want to pee more and clearer. Stool is moving, but don't want to expel yet. Can I wait till it hardens?

Sorry this is embarrassing and unorganized. This is a lot harder than I thought. I will make a new account because this one wasn't suppose to be so serious. In case people don't know by now, I am a 21 year old guy because I never responded in my thread and didn't want to cause confusion. People call me Blaise.

I'm sorry Sacristia/chiron for not responding but please wait until I get this sorted out, my brain is tired. I apppreciate your responses so much and to anyone who can and has given advice, A HUGE THANK YOU.
