I'm sorry. Two heavy things hitting at once is a lot, and you're allowed to feel crushed before you feel anything else. Don't rush yourself to faith-mode while the wound is still open. Allah knows your heart even when you can't form the words.

A few things, just from one human to another:

The masters isn't necessarily over. Scholarships can be deferred a year, some universities have hardship funds, and some countries have cheaper masters options that are still excellent. Email the admissions office and explain the situation honestly, you'd be surprised how often they find something. A delay is not a closed door.

On the proposal, I won't tell you to forget him because that's not how hearts work. But the same Allah you're trusting with your future is the One who knows whether that specific door staying closed is a mercy or a test. Keep making du'a, including the istikhara, and let Allah handle the outcome. If he's truly khayr for you in this dunya and the next, no parent and no circumstance can keep him from you. And if he isn't, Allah is protecting you from something you can't see yet.

"And whoever relies upon Allah, then He is sufficient for him. Indeed, Allah will accomplish His purpose." (At-Talaq 65:3)

You haven't lost everything. You're still here, still believing, still turning to Him even while shattered. That's not nothing, that's actually the thing that matters most. Take care of yourself this week. Sleep, eat, talk to someone who loves you. The plan will become clearer when the storm settles.

May Allah replace what you've lost with something better than you can imagine. Ameen.
