Is my clutch shot?


I have a 1993 Mercury Tracer Wagon and I think my clutch is done for but I want to see anybody else has any other ideas.

Here is the situation. I replaced the clutch about 20K ago and haven’t abused it too bad. EXCEPT I live on a hill . Earlier this year my emergency brake stopped holding tight so I have been putting the car in gear to make sure it to charge down this hill. Recently it feels like the clutch is slipping. It work great at low RPM but a higher RPMs it revs and slips. Of note is that I don’t smell anything like burning clutch when my last clutch died.

I was hoping that I just messed up the positions or the clutch or something cheaper ? Any ideas?
