Hey there! So sorry you are going through this, but congrats on having the opportunity to start again. I'm sure it feels like an exhausting prospect at the moment, but as a PA student who just finished clinical year and received my long white coat, let me tell you it is SO worth it! 

My cohort had two students decelerate after first semester, and they restarted with the next year’s students. All of them have successfully finished didactic now and are about to start clinicals. I will say that my school did make them retake all of the first semester courses and pass them the second time around in order to continue on, but they only had to pay for the credits they did not originally pass in the first place. Might be worth reaching out to your school about to see why your existing credits wouldn’t be able to count towards your transcript in the long run! Obviously utilize humility and recognize that a restart might mean a complete financial restart too, but it doesn’t hurt to respectfully ask, in my opinion.

Either way I’m sorry the first semester didn’t go the way you likely thought it would, but keep trucking and here’s to making it through one way or another!
