Post-Interview Denial Blues - asking for feedback?

[sleepyjoey]

I had a good interview at an Ivy last weekend but got a denial email. I haven't gotten any other interviews this season and am pretty beat down. However not giving up am planning to re-apply for fall 2016 and spread myself far and wide.


I sent out 7 applications this year, only had one 1 interview which was denial. Would it be worthwhile to ask for feedback from my denials? 


Has anyone actually gotten valuable feedback from a denied school?


Thanks,
