Having ADHD with CPTSD around Neurotypical people😓

Idek where to start honestly. The past year I feel like I've grown so much and, yet I still feel so othered. There's certain subtext in conversations I don't understand, the very direct and blunt way I talk because I'm extremely literal, and feeling like I'm being super hypervigilant in areas I don't need to be. 

I also kind of feel like I accidentally offend or irritate people a lot because of the questions I ask. I really don't mean to be and I really do try not to be "brutally honest", just blunt (I feel like "brutal honesty" is just an excuse to be a very mean and/or shitty person).

Anyways, I guess I'm trying to say that even though most people I come across tend to love me it still feels so isolating because, I don't think like most of the people around me. Even with other people who have ADHD, I feel like I'm not understanding something crucial all the time or I feel dumb. I feel like people consistently have to mansplain things to me because I don't just take anything with a grain of salt. I have to analyze everything I hear and say.

Omg sorry if this got a little odd or hard to follow. I really just haven't been able to get this off my chest, loll.
