Everyone has days like that, I had one yesterday while I was playing with my boss (which made it worse as I couldn't get outwardly angry at myself).

Judging from what you've said there I would think that your putting is hurting your scores more than the 10% you think. Also a solid short game will help you. My instructor always tells me that noone, pro or amateur, should ever have anything more than a 2putt. If your too far out to have a good chance at holing it at least put it somewhere where you know you can make the second putt. For instance 3 putts on the 9th from 7 feet, that should be 2 putts at most, if you miss it should only be a foot or so from the hole but that comes with practice and knowing how hard to hit the ball. Other thing is the short game. Get out on your practice green and at the range and practice all sorts of shots from 100 yards and in. Practice full wedges, chip shots, flop shots. Practice little finesse swings, bump and runs. Practice any shot so you always have a shot available to you that will get you within a few feet of the pin. Getting annoyed with yourself is not a bad thing so long as it is constructive. When your out on the course don't think 'argh I stuffed that chip up I suck', think 'argh I stuffed that chip up, I need to work on that later'. If you have noone behind you don't be afraid to put 4 or 5 balls on the ground and keep hitting those little chips or pitches until you get it right. Once you get it right hold onto that feeling and do it again.

Also for what it's worth I think most people would have shot far worse than you did after only 10 rounds. In the many years you play the sport you are going to have ups and downs but it those straight drives and well hit wedge shots are what keeps us coming back. If we all played better each time we played we'd all be on tour by now.
