I just got done working out for an hour and a half. Burnt 933 calories. I did a little stomach workout as well. I only had a cheese stick and yogurt for breakfast. I drank two 16.9 oz waters. I had a cheese stick for a late lunch (not hungry) and now I feel kinda sickish.

Well yea. You didnt get enough calories to burn all that up. Go eat. I crash like this too if I dont get enough calories in.

Extreme eating wasn't good for you...and extreme exercise isn't either. (nor is extreme calorie restriction)

Work on moderation and making loving decisions for yourself. Think of yourself as some other person you have to take care of. You'd never make them work out until they were sick, and you'd never overfeed them to the point of being unhealthy. Do the same for you. You're worth loving, thoughtful care taking.

Moderation is normal and healthy. Make the new normal....more normal and less extreme.

I'm sorry you feel this way. I hope you ate something & are feeling better. Good luck!
