Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread.

Go on with your life.....get counseling. Sharing DNA does not give anyone the right to abuse. WHAT YOUR AUNT DID IS ABUSIVE. Run for your life.

Your aunt will definitely try to contact you. I don't know when.....but I assure you that she will.
Don't answer her call. Let it go to voicemail and then delete it without listening (I know it's tempting.....but don't. It will weaken your boundary cuz I assure you, it will be all sugar coated and full of groveling).
If she comes over, don't let her in. Tell her to leave and never come back or you will call the police.
Don't go to facebook and read her "smear campagne" cuz she needs to get peeps on her side.....let her.....just ignore her and stay away completely from social media.
If you have good friends concentrate on them and make new friends.
Fill your free time with positive adventures, hobbies, and people that are good......it's rewarding and time and energy well spent.
NO CONTACT is just that.......never!!!
Best of luck and know you are not alone in this. Know and be on your guard that going no contact will indeed tic her off. First she will attempt to be nice, but will soon turn ugly and painful.......just hang in there and never give your power away or you will become a victim in life.
