Odin Project and freecodecamp were highly recommended on Reddit a couple years ago, no idea if that still holds up. Worth looking into. Colt Steele/Udemy/paid courses you can't guarantee are up to date suck because of low effort updates to outdated content.

MDN (Mozilla Dev Network) is best for detailed documentation, and has plenty of small lessons but no actual bootcamp/course. Avoid w3schools except for reference documentation; they have gotten better, but there's still plenty of simplified examples that are bad practice like inline styles and event handlers.

One of the first lessons from good teachers is to not compare yourself to others, as everyone learns differently. Only compare yourself to your past self. Programming is extremely complex and usually doesn't "just work" for the brain, so any progress towards understanding is great.
