Thanks for the advice I'm starting today I think I'll try doing the combination of lessons and solos so I don't get so aggravated at myself so much my main problem is I have to deal with PTSD and get angry alot but I watch these guys/girls and they make it look so easy but I also know there is a starting point just breaking through that I think is going to be an ass kicker lol
Well try to get a good technique on the right hand, since it's doing most of the work, and it's very important for synchin both of your hands. i would practice the motion first without playing any note and then start to adding some notes.
Also like everyone said use a metronome and start slowly, for this technique is super important to not develope any bad habits, so play slow to get the right motion for both your hands and slowly start increasing the speed. Im not gonna lie to you, this is one of the most time consuming techniques so you will have a good time on it. But you will get no doubt of it
