We’ve turned into a Hive, things are getting serious.

Pay a huge amount of money, get a high chance of becoming disabled for a negligible chance of holding hands.
But then they will face the reality that the problem is not in height, but in the head, which needs to be fixed. And they will have to pay another huge amount of money to a psychotherapist, who also will not be able to guarantee a result.

The problem is in height, hence the problems in the head. So, most likely, things will also improve in the head after increasing height. And the chances have definitely increased, possibly even by a factor. At best, a psychotherapist would teach him to accept and endure the fact that he is short. At worst, he would advise him to find a girlfriend with a face mask from a child.

I hope he has money left for jaw surgery, otherwise he's still doomed.

The jaw is overrated. And height is really very important. Between a short guy with a prominent jaw and a tall guy with a weak jaw, they will choose the tall guy (with the condition, of course, that it is just a small jaw, and not an ugliness). In addition, the most important thing in the face is the eye line. If nature has ruined it, then no jaw will save it, it really is doomed. Unless you can compensate with height.
