regret is destroying me

I'm pursuing ece at dtu. i missed iit by few marks. i didnt join any coaching or anything did all the prep by myself like doubts ke liye bas yt videos dekhte tha(i watched video on yt for doubts only) .
The regret is so high that it's been 8 months i joined this college but, im not able to move so, im thinking to give LEEE(lateral entrance test for iiit hyd) and join IIIT Hyd. cause i wanted iit or iiit hyd.
but, the problem is DTU is best for me, i want to do startup and dtu incubaion center is quite good for it, the free time dtu give it's just really helpful.
placment too r good like 16.5 to 18lpa with around 80%.
With IIIT Hyd building a startup would be really diffcult cause of acads.
choosing IIIT Hyd is not a good option cause of mutliple reasons but, still idk why my mind is saying that.

Cons of IIIT Hyd for me:

1. Fees(im from middle class or can lower middle class)
2. Free time for startup(one of the most powerful con)
3. I dont need any MS degree with LEEE u get a dual degree cousre is mandatory
4. few more cons but, these r main ones

idk just help me with this.
P.S: i was a dropper

Due to some reason during my prep u can say maybe tragic stuff i missed iit

I was doing hell lots of hardwork no coaching no guidance. No one in my family was much interested in studies. I faced so many difficulties during my prep. Each time i used to imagine myself at iit or iiit hyd which used me give me a push. Cause im not iit or iiit hyd my mind is constantly saying u failed even after so much hardwork.
