Need some advice

So placement season was tough for me earlier I used to think I'd easily get good package (like my expectations weren't too high 8-10lpa) got ghosted by a company after clearing all round for 8 lpa .Skipped many companies between 6-8 bracket due to vague description or not good reviews available . I managed to crack a 5lpa mnc but the thing is I got my location as chennai and I'm from north having never went too far never imagined myself living outside the zone and I'm very emotionally attached to my parents and home, the very own thought of leaving them for this far has affected me so so much I have my flight tomorrow and I haven't eaten properly from 4-5 days it's such a horrible feeling . What should I do how should I get myself up again , I've gotten so much upset that I'm starting to think if I'm good enough or can I get even get clients or do I even know anything .any help would mean the world to me
