In light of my nearly one year experience on r/short, I don't think it is a self-suppotive group at all, for it is really congested with complaints, ventations, blackpills, incels, etc. And rare posts are offering constructive suggestions/advices, or just talking about what short men/women have successes in random fields like dating and everyone mentall jerks off to them.
It's really... boring and noxious.
I don't think venting itself is a waste of time, but venting must be a part of self-supports, not the main or even full component of them.
So I built a server which contains ventations but also limb lengthening surgery discussions, height increasing method discussions and off topic sections. So I think this server is very constructive.
I don't agree that the following is relevant for this idea: ''Members complain about height discrimination and how being short sucks, but never reach any real solutions.'' This is not a reason to not think of a group. Because the ''website'' of a group like this wouldn't be a solution obviously to be tall (we let that to this forum) but could be supportive if well moderated and with good contributions about a thousand things for short people and of any age.
Because there are people that can't afford, are afraid, or just don't want to do CLL and some don't even hate being short, specially girls.
I remember that old website (''short people'' something...) had lots of contents about sites where to find short people dates that don't care about other's height very much, elevator shoes (with disount!), activities and sports best suited to short people which can make them (us) feel better and well acomplished (besides, physical exercice helps depression in which short people tend to fall a lot), just sharing (''positively'') a bad day, how to adapt your house and car ergonomically, how to react or respond and ''kill''' immediatly bad and agressive comentaries against short people, a display of psychologists and psiquiatrists specialized in body disphoria who can participate and whose research can be publicized (or even finding support from them).
Regarding psychological suport I even think absolutely that all of us thinking planning CLL should have psychological support. It's proven that a change in the body, for good and for bad, creates issues and chalenges very frequently, and it would help the hard surgery and recovery anxiety, as well as return to the ''new life'', relating to others, etc., People benefit absolutely from that. Some surgeons even make it obligatory, etc.
I have several ideas for sharing with people and as we all know two or an hundred brains work ''better'' than one...
Plus, it could be a ''preparation'' in psychological terms , to CLL.
The other site lasted for many, many years, but was a bit old fashioned, people got old and probably abandoned the maintenance.
But it hasn't to be like that, and the positive thinking and optimism tends to ''replicate'' itself, it could be a good challenge and definitelly very useful.
