Has anyone with DID ever experienced this or know a way to handle it?

I feel like I've only been in this world for the past year on and off, due to a combination of therapy and anti-psychotics, which have made me dissociate less. That's great and all in terms of recovery, but I find that when I'm in this world now (not dissociated), after almost 30 years of living in a dissociated state, I get WAY too overstimulated. I feel like before I was just watching life on TV and now I'm actually watching real people and am a part of it the real world. Again, I know it's a good thing in theory, but it's making me feel crazy! It varies, but I often only last like 20 minutes at the mall. I can't make plans with anyone because I don't know how long I'll last out in the world. I usually just stay at home, other than work. Work is suffering lately because I work in a public library with LOUD kids. I get super irritable because I can't handle the noise. I've just been drugging myself with Klonopin to the point where I'm getting addicted to it and probably shouldn't be driving to work on the drug, but it's the only thing that turns down the volume of the world. Anyone have any insights?
