Have you been to see a mechanic? They are better able to diagnose issues like this. All we can do is guess.
I try to do as much as i can ...i think i going to have to bite the bullet
Have you checked/felt the radiator hoses?
top and bottom,
Give them a feel,
is one cold?
Blocked radiator
Failed water pump
Water pump drive slipping
Failed thermostat
Failed radiator fan.
Airlocks in cooling system.
WE cannot diagnose from a distance. You need a competent mechanic..
