I am extremely sensitive to mean people even if what they say to me is something small or passive aggressive. Even though they belittle me without using swear words or derogatory terms I still get hurt over their comments

I feel like crying every time someone is a bit mean to me and I just obsess over their mean comments and feel really bad about being so dumb.

I have a history of really bad social anxiety that made me fearful of people so I also find it really difficult to interact with people. How does one shrug off mean comments and not cry over every single little mean thing?
