My OCD, anxiety and ADHD stack

Diagnosed with OCD and ADHD, i also have speech blocks, which is a form of stuttering.

My OCD is mainly rumination. It excaberates especially when I'm excited or happy in general. Example: Talking with an interesting friend, winning a match in fifa, doing well in classroom and understanding everything. That is especially when the ocd flares up. It is sort of like anticipatory grief but worse.

I get stuck in compulsive loops. No matter the logic i give, my mind will not have that "Ok got it" feeling. And what happens afterwards? The anxiety takes over and depletes the interest and motivation.

For speech blocks, this one is cheeky. It goes away in certain situations or for a short period, but then comes back. This overly flares up when I'm excited aswell as normal situations.

For example, i won 3 debates in my school. But would stutter or block over telling this to my family.

My dad has a stutter problem too, but he consistently stutters, whereas i do not stutter or block AT ALL when I'm talking alone, invested in gaming with friends, or when i feel overly confident.

It has gotten pretty worse now. Imagine not being able to communicate without blocking every 2-3 words and replacing them with something else, and sometimes the replacement is an obnoxious word that ruins the setting and tone, leading to even arguments.

I also have bloating and my dad has heavy bloating too.

My stack that i'm considering: 1800mg NAC, Magnesium biglycinate, 10-12g Inisitol, and omega 3

I'm also taking Ritalin XR, which works on my ocd and adhd for 3 hours, but then stops working, it should last 8 hours right? (Although i take addwize)

I have tried lexapro and fluvoxamine and it didn't have any effect. L thenaine didn't work too.

Should i add taurine to my stack? since i need something that is instant because all of the things above will take time to work
