Hi Katrina, yes, that precisely... I have to learn not to get frustrated with my over-expectations of what I can do... and set reasonable goals, and continue on my path of healing with its ups and downs. Still needs to fix. A digital piano? how exciting, I'm self taught... first learn chords to sing alone with a drone or string sound and for learning I think (many years ago but I guess it might be still up) I remember a guy or channel called "Lypur" it was more oriented into teaching music theory but I think it was also a piano learning tutorial (like the first two years of conservatory for free or so) anyway youtube you have all you may need to get started. Have fun!
