My brother has told me how ridiculous it is and that I need to stop getting so hurt by these pointless things. Basically I follow a lot of Dog accounts on Instagram and when I comment "good dog fren, u a gudboi", I feel rejected by the account holder because my comment wasn't liked or replied to but others were. I create a lot of scenarios in my head where these people just don't like me but that's not true. 

Most take their time and reply which I'm grateful of.

However when people don't reply on Facebook it still sucks but I've got desentzitised to it.
