Hello @HeWhoWanders, welcome to the forums.
I'm not really certain where all the anger and frustration comes from. Is it because you can't beat one hard AI after a week of playing? It's certainly possible, but you might need more experience. If the previous replies didn't give you enough to go on, people here will answer questions, but just ranting and generally saying that your attacks aren't successful aren't good cues to give you hints.
