Hey Anna! I was rejected from every school I applied to last year. At first it was really disappointing and slightly disorienting. So, I took this past year as an opportunity to really reconsider my reasons and motivations for getting an MFA. I then planned my year accordingly, I attended some workshops/concentrations at craft schools to develop my skill set and sought out specific mentors to help in my conceptual development. Overall I feel much more prepared and grounded this time around. Also, through immersing myself in lots of different creative communities I was introduced to programs that I feel are much more appropriate for my overall long-term goals as an artist. I would suggest, if you actually don't get into schools this time around, to take the next year really seriously and look for some opportunities to push you and provide more support and insight into your practice.
You also don't have to explain anything to your recommendation writers. Grad school is competitive and people are aware of that. Also, most schools save your letters of rec for a whole year, so you can re-use them if you intend on re-applying.
Good luck to everyone!
