Does anyone have any tips on playing with both hands?

I know what آپ meant about the fustration of not being able to play a piece especially when آپ practice all the time, I get this all the time!
The only tips I can think of is to make sure آپ can play each hand seperately almost perfectly before آپ try and play them together. Also I find writing on the موسیقی helps, like draw a line between the left and write hand notes if they're played at the same time یا if one hand is played first draw a slanted line from that note to the note in the other hand that is played afterwards (hope that makes sense?). Also play it really slowly at first. Hope any of that helps :D
