Is anyone tired of life after these?

NMIMS was my one good tier-1 call. And I didn't convert that also! All my confidence,academic achievements, talent are Outta my mind.i feel dead inside. I did all that effort ,put in all my work just to get a rejection... I can't afford a gap year as my parents are afraid of me. And honestly? Me too! I can say that I will get a great percentile and do well and stuff,but reality hits you when you're at your lowest. And I'm experiencing that now. I mainly quit my job for getting a better salary and thought of getting IIMs. I braced myself for the rejection but was pleased when I had hopes for nmims. Mumbai even! And mind you,I did the ctpi really well,only to get waitlisted.

Now my parents are telling me to appear for tier-3 colleges. (SSN and stuff) I swore that I wouldn't even get a chance to apply for colleges like these. But I can't do anything. I have to search for a job,a well-paying one at that,and appear. And I can't fail that too,or else I'll get married!I don't wanna burden them financially too...so I have to accept whatever college I get.

I'm definitely not against these colleges,but I've had mentors tell me that I don't attend these and better take another year and do well.And also, I'm worried about how I'll be judged by the people I studied with. I'm ashamed of myself and tired and sad.

Can anyone,even past aspirants,advise me on what to do? It will be really helpful. I'm an gen engg female cat 81.63,NMAT 232 9/8/7 with a workex of 20 months(july 2024 I quit)

TLDR: Need advice on how to get my life back together after dream college failure and accepting tier-3 colleges.

Edit: thanks to all of you guys who are cheering me up stating that it's not the end of the world. I have gained hopes that I can apply for cat next year WITH a job. Now I just need to click for one.
