My mom is an education professor. She has taught both graduate classes and undergraduate and honestly in the program where she teaches there isn't a ton of difference (if any in some classes) between master's level and certificate level.

I know it's not going to be easy but it is something to be so proud of when you finish and you've been doing so well with stability for quite a while that I think you can trust yourself.

And when it is stressful there is always support here for you.
