1987 Toyota Supra my clutch pressed in but didn't come back out

1987 Toyota Supra mileage: 130,000. Three months ago, my clutch pressed in but didn't come back out. I called my mechanic and he ended up replacing a seal and another part (can't remember). This did the trick until this morning when I went to start the car and the same thing happened. I checked fluid level and was almost empty, filled back up but clutch still not responding. Do I need to bleed line and how do I do this, or is it something else?
