I bought 5 lessons to learn how to drive should I buy more?

I’m 25 and I still don’t have my license. In the past people kept telling me that I don’t need one because I always have a ride. I also don’t have a car because I don’t have a license. I want to drive really badly and I currently had my third lesson. I was told I need to practice in between lessons so that I can learn thoroughly. I’ve only bought 5 lessons so I have 2 left. My instructor says I am a good driver but I have too much anxiety which leads to me holding the wheel too tight. Do you think I need more lessons?
