You've not crashed your car yet. You've not been convicted of a motoring offence.
You're on target to get your first year's no claims bonus.
So far you've been a good enough driver.
It's much better that you're an alert safe driver than an over-confident / inattentive driver.
I find it easy to stall low torque manual petrol cars. Stalling is no big deal. It's just a case of adjusting your muscle memory to reduce the stalling. And, of course, reacting in a safe way to a stall.
Some people over-rev low torque manual petrols to avoid stalling. The trouble with that is the clutch wear.
The extra lessons suggestion from Georginadoll is a great one. Many instructors teach their pupils how to pass their test. Find an instructor that will finish off teaching you how to drive well.
Apart from that, carry on. You'll be gaining more and more experience as you drive.
Please don't get like certain friends of mine that refuse to drive on the motorway. Or are very reluctant to drive at night.
When your insurance premiums come down, you could look to swap your car for an automatic or a diesel (higher torque engines and therefore easier to avoid stalling).
Your parents have unreasonable expectations. I bet they weren't so brilliant when they first passed. Ask them about their accident and convictions history.
