I don't know what else to tell you other than to get a adapter shield made for your screen, instead of trying to wire it yourself.
thats what i'm going to do
hope my screen isn't damaged in the first place
Just for the case somebody read it in attempt to solve a problem with touchscreen:
check your 5V level.
Some USB ports have not enough power, and touch sensor seems too sensitive to low voltage.
