You could take lessons. A teacher will guide you through a progression of what you need to learn, in bite size pieces so you don't get overwhelmed.But we know that's unlikely.Next best thing (well, really, next least worst thing) you need to buy a "method." That's a book for a beginner that starts easy and progresses. Alfred's Adult Basic Piano would probably remove a lot of your confusion. Don't skip around, start at the front and work to the end of the book. There are other similar books out there. https://www.amazon.com/Alfreds-Basic-Adult-Piano-Course/dp/0882846167But you do need to get away from a touch sensitive keyboard and into weighted keys sooner rather than later.
do be sure to also play things you like on the side - just for fun.
Where has musical education gone wrong ?
Twelve years or more ago, when I started posting on piano forums, it was largely for selfish reasons. But since then I have received requests for help from hundreds, I do not exaggerate, hundreds, of mostly young, exceptionally talented people, who are desperately unhappy in their pursuit of something which, by rights should be an unconditional joy. Regrettably, I am not good enough at either classical or jazz to give any help in those areas; I wish I could. In the creative aspect, I have been able to free one or two, and that has been a very satisfying experience, perhaps more so, in its own way, than my personal playing.Playing the piano should be a dependable liberation of the spirit, consciousness, the soul, whatever you like to call it, not a despairing, neurotic battle for breath.

Basically, I need someone to give me a guide plan for things to work on, or even just one thing to practice or learn, something that I'm missing that would allow me to feel more confident on the piano, perhaps a really good website or youtube series that I can trust to take me through what I need to learn.Thank you.
