Does anyone else get paranoid posting personal/ mental health related things?

My sister knows my reddit username but I told her to never go on it and she said she doesn't. She's not the kind of person to snoop but sometimes I wonder but in all reality she is so wrapped up in her religion right now that I know she would not maliciously or even out of curiosity look at my reddit comments. She doesn't even go on reddit other then prequelmemes anyways and I doubt she knows that my name on here aclockwork0range is spelt with a zero instead of an o. So I post to my hearts content. The comments I do delete though are things that I don't want really any one knowing even with how anonymous reddit is I know no one in real life would read it but having everything in your life shared on a website is not how it should be even though throughout the years at least a good chunk of my life has been shared on here only in hopes of helping people maybe relate to what happened to me so they don't feel so alone like many of you kind people on the bipolar subreddit help me relate and feel less alone in this struggle with our illness.
