I currently Dropped all my semester after my suicide attempt. I overwhelmed myself so much that i just broke in peaces. School can always be put on a back burner, I know that stuff Like that seems like a priority but your metal health is more important.

Can you take the Class Next semester ?
will the world End if you don't take the class ?
Is there a Specific date you are mandated by the state or Certification board to get certified ?

Don't stress to much over things like this
There is plenty of time in the world to finish
Don't let your own shadow push you off the ledge.
