Help me finally start keto!

I (20F) literally just need any form of encouragement to start. I've done the grocery shopping, just letting everything marinate so I can cook it and start first thing in the morning. I think I'm just afraid that I'll be doing everything wrong and thus wont reap the benefits of the lifestyle. My main goal is fat loss, I'm so tired of living in a body I'm uncomfortable with and don't wanna waste time anymore.
