Feeling off: tremors, weakness, loss of appetite... what could it be?

Hey guys,
I’ve got a bit of a situation. I've been shaking like crazy for a few days now—not all the time, but mostly at night. It settles down if I take a sedative or just try to chill out myself.
Yesterday I felt super weak too, couldn't even keep food down. Went to see my doctor, ran blood work, checked my blood pressure... everything came back totally normal.
I have no clue why I'm shaking like this... anyone else ever dealt with something similar?

Well, looks like it could be nerves. What’s the doctor saying?

I don't know. My doctor gave me a full checkup and said everything looked fine. But I only went in because of the shaking, not the loss of appetite.
You think it's just nerves?
