I have created a group for people suffering from CPTSD and other mental illnesses on Signal. I can share the link if the post gets approved.

Feel free, but be careful that your group might be overrun with spammers and other malevolent people
And people with issues giving advice on other people's issues when they can't even help themselves. We have professionals that study this stuff hard for a reason.
Would a Matrix channel be a better option? Just curious.
I think thats an awesome idea but make sure that you are careful to facilitate a healthy space- its very easy for spaces dedicated to really awful parts of the human experience to become so overwhelming in their negativity that they're kind of a toxic cesspool making it harder for people to make their peace with things and cope effectively, rather than easier
Sadly I don't have access to signal at the moment, but if it exists in other forms, I would enjoy joining.
Though your place is probably more ready to serve the purpose, I also have a Discord group that is happy to partially also serve as a counseling haven.
