You know if you were perfect, you would not have been here. Mistakes and errors are what makes us mortal, death makes life itself imperfect. When God made mankind, he gave room for a lot of errors. I don't think there is any great person who ever achieved anything without first failing a couple of times. The only difference is that for every fall, they always rise wiser and smarter.
It is okay to make mistakes, exhaust all your options, you can even threaten to give up (as long as you don't), become frustrated. Because at that point when you yell and say "I can't do it" that is when your will comes alive and a stronger version of you is born. But when you don't try, just because you are afraid of failing, how would you then know your true potentials?
In essence, it is ok to fall and hit rock bottom, fail as many times as you need to succeed. Because in the end, it does not matter how much you failed, it does not matter how many times you wanted to give up; the only thing that matters is your ability to keep pushing.
