Time to take it to the shop! You have already done about all you can do.

Radiator flow is either restricted by a blockage or the water pump has failed. Take to a shop for a diagnosis.

Thanx so much for the advice guys I appreciate it!! Any idea how much that will cost me im kinda on a tight budget and would that be why my heat has been acting up blowing cold air instead of hot?

This info. would have helped in the diagnosis. Turn on the vechicle and run till it warms up. Then touch the inlet and outlet pipes on the heater core. They should both be warm or hot. If the outlet is a lot cooler than the inlet, your heater core is plugged or the valve has failed. These pipes will get heated up if the coolant is flowing. They won't heat if the coolant is not circulating. Best to take to shop for the flow test.
