Let any worries go (for now). They might have resolved themselves by tomorrow and, if they haven't, you'll be able to deal with them then, using any support you need or entitlements you deserve.
they는 worries이고요
질문은
내일을 추측하는데 might have resolved 는 시제가 틀린거 아닌가요?
그냥 may resolve 또는 might resolve 로써야 맞을거 같거든요?
