2008 Suzuki Vitara Oil

So I was going out our town, and I decided to just change the oil (just oil) in my car. Since my trip was like four hours away I decided when I come back I'ill change filters and plugs bal bal. So I change the oil right? When it came out it was like waterish, but it had some thickness to it. So my car start shaking lightly so I knew it wasn't normal so I take it to an oil change place and they said I over fill the oil tank, but I thought to my self how? If I drain it and put 5qrt oil. That's what it said in the direction? So I go drain a little gallon. As I turn it on I decide to go to the corner store witch is like 30ft from home. And it starts pulling I automatically taught I drain something else I need help I need to know if I did drain something else or something went wrong?
