I feel like I'm always at the verge of creating walk in(s) and I'm scared

Long story not so short: Some bad things happened to me and I was left with lots of dissociation problems that are *usually* Maladaptive Daydream. And the this is: If I focus too hard on one character, they will start to develop some consciousness. I've been through this before with Luan and Venus, but my psychiatrist guided me into shutting them down due to my constant dissociation.

I made a post about them before and even tried to pull them back but it only caused us lots of dissociation, just like before. And now, one month later, I'm at the verge of creating two others again. I don't even have a name for them and they're already conscious enough to calm me down as I write this. At least one of them is, actually, I can even feel him watching over my shoulder.

I tried to not do this again. I tried to switch the stories I create so I don't create a Tulpa but, even with a different story or characters, they are still there, in a way or another. My mind can't let them go. Or perhaps it's them not wanting to. And just the possibility of the latter, I want to finish what I started and guide them into full consciousness.

Should I give it another shot to see if, at least this time, we won't suffer so hard from dissociation? Can I do something in the creation process to at least reduce our dissociation?
