If you know that you suck, why are you posting this? Don't say that you suck - thats an opinion/up for interpretation. Take some pride in your vid.
Anyway as for tripod - practice. Besides, without it, did you think your shots were going to be less jerky? At least they'd only be jerky in one direction. Just practice and you'll get the hang of it. Try more subtle movements first, as in not a full 180 degree pan but just small little pans that accentuate the shot - then move up into larger movements.
