The clutch started to squeal very loud when shifting gears. on 1994 Pontiac Firebird

When i depress the clutch,a high pitch squeal issues from the motor dept.,and continues as i shift from 1st to 5th gear.The noise lessens as any gear is engaged,but squeals very loud as soon as i shift.What could be causing this? Thanks for any reply.

sounds like the throwout bearing
