I'm feeling like a massive failure and feeling lost right now due to Grad School rejections

For Grad Schoo, I applied to five schools for a masters and I got my last letter today which ended up being a rejection. I was on the waitlist for it and I had high hopes and I got rejected by all my schools. I do have a backup to do my masters at my current uni but honestly, I feel like a total failure and that all my hardwork was for nothing. As well, my brother got accepted by almost all law schools he applied to, so ngl, I’m feeling kind of inferior to him and worry that even if my parents won’t say it outloud, they’ll look at me/consider me to be the failure/screw up. I admit, I was kind of scared of what do to next after undegrad and sad corona ruined it, but I feel like going back to my old uni will make me seem like that old slacker loser who is afraid to take responsibility and trying to relive his youth or something. I’m feeling lost and unmotivated now tbh

You’re not a failure. It’s alright to be disappointed.
Don’t compare to your brother. You are a wonderful, unique person.
There are better days ahead even at your current university, even following your back up plan for grad school.
There is a blessing in disguise that will reveal itself in time.
You’re going to be alright, whatever you decide. Don’t let anyone make you feel bad, don’t let them mess with your mind.
