It sounds like you are doing all the things you can be doing, so good job on that. Missing EA deadlines makes it tough…schools won’t know who from EA is committing until May 1, and assume nearly 100% commit from ED round(s).
I know getting denials and deferrals is stressful, as is the waiting. If you don’t want to put in more apps (which is ok), there’s not much more to do. Try to keep busy doing things you enjoy and focus your energy on things in your control. I wish you the best of luck, and please keep us updated.
