How do I deal with constant rejection from auditions?

You can audition well, so the problem is not your ability anymore, it is the sheer volume of nos, and how each one chips at you even when you did nothing wrong. That is the part of this life no one prepares you for. The skill you can build. The steady stream of rejection you have to learn to survive. Here is what makes it bearable: most nos are not about you at all. You get passed over because you were too tall, too young, not what they had already pictured, a hundred things you could not have changed and never got told. Reading each rejection as a verdict on your worth is taking the blame for decisions that were never yours to control. The room is not judging your soul. It is casting a part. So protect the thing that has to last: your love of the work itself. Keep one place where you get to act for the joy of it, with no one deciding your fate, a class, a group, a project. That keeps you an artist instead of just an applicant. The rejections keep coming. What they cannot touch is the part of you that does this because you love it.
