Well brother, I can understand your situation. I know you have worked hard for JEE mains but I believe with 100k rank you won't be getting college. 

Though with OBC and home state quota, there might be an increased chance of your's getting a seat but with such a rank it is very hard to get. Your home state would be help you in NIT Warangal but to your luck, it one of the bets NIT's of our country, so oyur chances of getting that becomes almost zero. Had you have home state quota of Assam or Raipur, it can bring some relief to you.

So, I would recommend you to take part in JoSAA and go to through all the round even the spot round

Thank You
