I tried once with a character specialized in speech and firearms didn't exactly work well, can someone reccomended a build for charisma that doesn't absolutely screw me in the game

Firearms are tough for new players. In fact, they're not particularly effective even for experienced players, which is a bit disappointing. A more effective weapon skill is throwing, or melee. Throwing is nice because your boomerangs and charkrams don't use up ammo and don't get damaged from hitting enemies. Also, you can use grenades, if you are tech aligned. A single point in the explosives discipline is enough to make molotov cocktails out of trash you find in garbage bins, which is pretty cool. Or if you prefer melee, that's as simple as putting a few points into it and also getting some Dexterity.

I haven't tried a Charisma-focused build myself yet, but I gather you want to spend points on Charisma and the Persuasion skill. A couple of points into your chosen weapon skill (e.g. throwing or melee) should be enough to help you survive in the beginning, and then you can recruit as many followers as possible and have them fight things for you. I recommend getting into either tech or magic as well, as it will make things more interesting. With magic you can pick spells to buff up your followers, or blast enemies from a distance, or many other useful things. With tech you could build grenades (which won't hurt you or your followers, making them very useful) if you use throwing weapons, or you could smith weapons and armor for your followers (and yourself), or you could mix up potions and tinctures to heal and buff your party, etc.

Others on these forums are more knowledgeable about how to specifically spend points for a Charisma-focused character, so hopefully they will chime in as well.

Just chiming in that I'm also just starting out and have had the same build idea (charisma, persuasion). Someone on another forum linked me a series of guides and this one looked promising - https://www.youtube.com/watch?v=w-7vaybvOS4 . I'll probably go with this one because it has everything I was looking for - high charisma, persuasion and enough magic to play as support for your followers.
