Need to rehome my depressed kitty!!!

I need to rehome my 6 months old female unspayed kitten coz I'm going to clg and my parents won't be able to take care of her. Bt since she went through a major sibling loss last month, she's been acting different than before (loss of appetite, more sleeping in hidden nd dark places).

I have been trying to give her an appropriate companion bt have failed to found anyone!!!

I have found a great known person who's ready to adopt her along with another kitten to accompany her.

So guys what if I give my kitten and another new kitten(be it male or female) to this person tgthr... without bonding or anything...

Idk much bt I was assuming that when they'll go to their new home they will eventually find comfort in each other as both will be in a completely new and unknown environment??

Can u guys tell me if am just having wishful thinking or if this really will be true?

What to do??

Also to note*** I'm short on time...like VERY much, coz I've already asked for a lot of time from the person who wants to adopt so tht I could find her a companion... however I'm very near to the "deadline" now!!!!

Am asking this coz Even if I find a kitten I wont have the time to help them bond...

Not a minor,

India

Vet is accessible and will be accessible to the person adopting as well.

Bonding issue??

6months

Female, not spayed yet, hasn't had her first heat either
