Find a level open space where you can check your clutch without any danger of running into anything.
Park your car with the engine running.
Firmly apply the handbrake.
De-clutch. Engage 5th gear.
Very s-l-o-w-l-y engage the clutch.
Can you engage the clutch fully without the engine stalling?
If so, your clutch is badly worn and requires replacement.
If the engine stalls immediately, then your clutch still has sufficient bite. Who knows for how long?
You may have a bit of oil, or something, on your clutch disc, or the disc may be glazed.
Try "burning it off" by doing a couple of aggressive launches, a.k.a. drag racing starts.
Good luck.
