I feel I've to act daily to survive

I feel like*

i just can't have a normal conversation with anyone without being conscious about how it might come across, and it's not always in a good way, it's like, maybe if i say this, i become less in that person's eyes. I know i shouldn't give so much shit, but the disrespect that i get from not being conscious is horrible. I don't know how to deal with this, i just feel like I'm always one word away from being seen as a easy person, who can be told anything and made fun of, without them minding what would it make me feel.
