Just one jerk from me, my line broke and my only fish got away.
What is the reason why this is making you feel bad?

It's good to keep practicing your skills in order to improve. If you quit now you'll only end up feeling worse.
No, I think this means that I should try to lower my skills.
You really shouldn't! With practice makes perfect, and with every mistake and error brings more expertise. You can't get anywhere without failing, so it's great to try and take all of these mistakes as learning experiences.
