All good suggestions.
But yeah - stop doing tutorials for now, I'd say.
Seriously, it is not a good idea to get hung up on a tutorial. I guess you've done the basic ones? So you know how to take off and land, how to navigate from system to system and from planet to planet, you know how to use the SRV (if you have Horizons),... honestly you know everything you need right now. Get into the game. Start doing some missions, fly around a little bit, you'll see it's not that bad. If something attacks you, run. Just hit the boost and then jump out of there. And even if you don't manage that, as long as you stay in the stock Sidewinder that you were given, you can die over and over and it won't cost you anything.
In a couple of days you're going to feel much more comfortable controlling the ship. Then, if you want to look into the combat side of things, you can try the combat training again and you'll see it's much easier.
