Oh boy do I know what you mean.
When I was using I told so many lies and was trying to balance so much bull ****. I was constantly on the edge. Approaching 60 days clean and the feelings haven't gone away. Its just become a habit. My mother calls my phone, I get a pit in my stomach. I hear footsteps in the house and I think somebody is coming to call me out. Whenever anything goes missing I feel the glare of accusation - even though I know damn well I haven't stolen or done anything remotely deceitful since I've been clean.
On one hand its weird to still feel this way, but on the other its a relief. At least now I know its all in my head.
