Learning to Paint and Feeling Lost

I started painting a few weeks ago after finding a local art class. I thought it would be a great way to express myself, but honestly, every time I pick up those brushes, I feel so overwhelmed. There's just so much out there, so many techniques, styles, colors, and everything looks amazing compared to what I can manage right now. It feels like no matter how hard I try, my paintings always end up looking like a kid's attempt at art class rather than something beautiful and meaningful. I don't want to give up, but sometimes it seems easier just to put the paints away for good. Am I doing something wrong? Or is this all part of getting better? Any advice or words of encouragement would be greatly appreciated.
