Welcome, Conrad! Good to have you here.

You've gotten some great advice above. It sounds like you've already figured out that frustration won't help you very much on your LDing journey. Learning to lucid dream can be a long haul, but you will be successful if you are willing to put in the work.

One thing that I find helpful for addressing frustration is bringing up dream recall a bit. Many (in fact, most!) nights, I do not have a lucid dream. But waking up with interesting non-lucid dreams serves as a great consolation prize for those nights when lucidity doesn't come. Furthermore, dream recall helps you build an understanding and relationship with your dreamworld and dream signs. When you build that bridge between waking life and dream life, it becomes far easier to be aware of when you've slipped from one side to the other.

Are you maintaining a dream journal at this time? If not, I strongly encourage you to make that a fundamental part of your practice. If you have trouble with recall at first, it is completely okay to write down just fragments or fleeting emotional residue that you have upon waking. Just make that effort to reach back and try to remember.

Keep us up to date and continue working through the lessons. If you have trouble bringing up dream recall, let us know what you're struggling with and we'll help you out. We've all been there!
