No.....I'm not "flcking around". I and others have been trying to help and guide you.
A slipping clutch will allow the engine to increase in speed while the transmission is in gear WITHOUT a corresponding increase in vehicle speed.
Typically, first noticeable in the high gears when accelerating. As the clutch becomes more worn the slip will be more pronounced and proceed into the lower gears.
Eventually, the truck won't be able to move from a stop in the lowest gear.
At this point, the damage will likely involve the flywheel, friction disk, diaphragm spring, throw-out bearing possibly other parts. Basically, everything between the engine and the transmission.
FWIW, I am not the only member trying to help and guide you to a solution.
