On the one hand that's really cool. On the other, I might recommend Matrix for something like this in the future, since Signal's really good for chats of two or several, whereas Matrix is Discord-esque for chats of many people.

See the pinned post for a long list of other communities dedicated to health or specific diagnoses. The list is continuously updated.
Nothing here shall be taken as medical or any other kind of professional advice.
Commercial advertising is considered spam and not allowed. If you're not sure, contact mods to ask beforehand.
Linked videos without original description context by OP to initiate healthy, constructive discussions will be removed.
Regular rules of lemmy.world apply. Be civil.
Matrix has better moderation features, if that is what you mean.
But personally I know no Matrix client that is reasonably responsive, all slow goo that is a pain to use. Signal is not optimal at all, but Matrix is kinda worse.
I think XMPP or SimpleX (very different approaches) are better here. XMPP better suited for public groups where you need spam protection
