Not Feeling Well

I am not feeling well at this moment. Hardly get enough sleep and took too much coffee as well. On top of that, I did not eat healthy food today. It's complete combination.. Don't you think so? I did something wrong and I knew that. I just can't stop it because at this time, I have a kind of stress and I don't know how to solve it yet. Maybe if the stress will be gone for some reasons, then I can fall a sleep easily just like what I used to be.
