Now I'm going to get angry that you're just playing Minecraft like that!

Ok, fun.

1. Nobody here will tell your parents anything because we can't even reach them.

2. Without any data, we can't answer your question.

While the game is loading, it usually never runs completely smoothly, that's quite normal. If it still jolts in the game itself, you either have not allocated enough RAM or your computer is generally too weak.

Yes, assign that with the RAM was the problem.
