I Am Learning to Drive

I don't see the point in me learning how to drive anymore. I'm too nervous to switch lanes. Everyone keeps telling me that it's all practice but that seems like an understatement to me. How can I practice? If I make one wrong move, I could end up getting someone killed. There aren't any second chances all the time when it comes to driving. Plus, what am I going to use the car for? I can't drive to see my friends because they live far and all of the jobs in my field are far from me too. I'll never afford my own car. I would have to use my parents and ask them permission to use and to tell them what for. So I don't have any freedom. It's like my parents are telling me to finally get my license just so I have a license and so they can tell relatives that now I can drive. I have zero motivation here. It's not fair that the world is too expensive for me to live in.
