So... you seem to have a few issues.
- It looks like your current character is a bad fit for both your own desires and the campaign. A character who's built around mental attacks in a campaign that's heavy on the mindless undead is going to be unhappy a lot.
- You find the rogue feats unsatisfying. They don't feel significant or impactful, and that's making the experience of leveling up unsatisfying.
- You look over at your buddy the fighter, and it looks like he's doing the thing that you want to do, but he's doing it a lot better, and this feels bad.
- You find yourself taking a lot of disabling hits (stunned, paralyzed, and so forth) and it makes you feel even less effective, and sometimes utterly useless, and that makes you feel worse.

So... there are a few things going on here, and perhaps the perspective will help you.
- Rogues in PF2 are not combat monsters, and Scoundrel rogues aren't even particularly combat-monstery as rogues overall go. They're more on the "skills and utility" side of the martial spectrum. Their time to shine is when you run into things that aren't combat. By comparison, fighters are focused hard onto the combat side of things. Combat is the one thing they do. Now, Rogues can fight, and they certainly can contribute as far as damage is concerned, but it's true that they can't generally outdamage fighters. That's by design.
- Further, as you've noted, a scoundrel rogue is a poor fit for a campaign that's heavy on the mindless undead.
- In PF2, trying to excel by being the badass that carries the party on the strength of your character optimization skills... doesn't work. There's a bit of CharOp to be had, here and there, but it's thin. Party optimization is much stronger. Look for ways to make your buddies stronger while they make you stronger, and you're wind up being a lot more effective overall. This is a significant break from 5e in particular (and even more of one from 3e and...
i think this is the best thing i have read about pf2e so far
but i want to clear some things up i understand that fighter is always gonna be the superior combatant and i think thats good i dident expect to be a combat moster it just feals bad to have somone in you ear talk about how litel dps you do and i let that in to this comversation so that a bad on my part when i typed it i dient even think it was gonna be a big part of the conversation i just wanted to vent a bit so im sorry for that
know back to charecter
i love the character mabey not his class but it fun to rp and all the skills and out of combat possibilities that arise but when i started i dident know faint was mental so that is part of my ignorans to the game
and just as a thing out of combat im having a lot of fun but combat is such a big part of what i have experienced in the game so losing not 40 min but lossing 4 hours because of a singel trap that every on misst with perception and then i roll a 28 fortitude saving throw and then im petrified and the im told by the dm out of game that i get to roll att the end of every day to se if im still petrified im gonna be honest i loos intrest
but to leve it on a positiva not i have been having a good time being the un offical healer of the party brewing potions and doing surgery
but i want to tank you (Sanityfaerie) for taking the time to type all this and puting me back on the ground and i might move my character more in to a passiv roll
