Hi Palobaseballer. I thought I'd share some thoughts. First of all, I don't think you should worry about a video yet. But I also don't think you should be too discouraged. I know 2 kids who pitched maybe a total of 10 innings each in their HS careers. One is now a starting pitcher for a D3. He didn't commit until after the senior season. The other is pitching for a NAIA school. Neither of these kids were varsity until their senior years. (What's interesting is that this NAIA kid is 6ft 2; 210lbs and can throw 83 with really bad technique. If he could finally learn how to block off, he could easily add 5mph.) Unless you are shorter than 5ft 8, I suspect pitching may be your the best route to pull off getting a college roster spot. So if you like pitching, go "all-in" with training under the supervision of a legit, knowledgeable instructor.
In terms of grinding out the flaws in game, it takes a lot of reps and instruction to correct things. Thousands. over many months or years. And the kicker is, when you get in a pressure situation, some old habit may still pop up.
I agree with the observation that you probably really love the game. Work hard. Putting in the work for a goal you really want is never a bad thing and you will be the better for it; even if for some reason you don't play your senior HS year or college.
