It does not matter how many attempts you have made at getting a full British licence, you are not a failure, more importantly not being able to drive a car manual or automatic unsupervised should in no way make your life less valuable. Even if your job or a promotion depended on passing the DSA test, suicide is just a sign of how easily you have given up on life. If you really want it, there is nothing that should be able to stand in your way, and irrespective of costs, number of times an examiner has said no, if you put your mind to it, you will do it.
You are not a failure, unless you throw in the towel. Some have taken 10, 15, 100 attempts at getting a pass, spent thousands of pounds, and there is nothing in life like finally achieving that goal after what seemed like so many failures.
Rather than thinking of committing suicide, think about the many other things you have achieved in life, and dream of the day when you will also get that pink licence, go and pick up your first car, let the roof down, and drive into the summer sunset. Suicide is not an option for those who really want to succeed.
