Welcome!!! I'm a little over a week post op so I'm no expert but my number one tip is that if you don't already see a therapist, start with one. Even if it's just your university health center one. Most of us struggle with our relationship with food and and that will probably never be cured, but getting help to manage all that baggage is invaluable. Also, just stress and fear from any life change can do a number and it helps to talk it out!!
As for recovery time, I would try to get the surgery near the beginning of the break so you'll have ample time to rest and do any assignments you might have.
