Sally,

Please heed what Mark has so clearly said.

Voluntarily letting go of that which puts you at greatest risk, i.e. field hockey, that aspect of your life as a college athlete ---
will be the far lesser sacrifice/loss/price-paid now, vs. what you may 'lose' down the road of life.
SO much is unforeseen ahead of us.

You've regained a great deal.
Do not risk losing it again, and potentially losing a great deal more.

Take good care of your brain.
It needs you to make that choice, so that it can continue to serve you with the excellence you've come to expect of yourself.

It's almost a given that we 'take that for granted' in our younger selves.
Be wise now in the choices you can make for your 'older self', down the road of life. You'll be glad you did.

Sincerely,
Theta
