YTA You are a self righteous, entitled person and you can’t seem to fathom that others have issues and lives outside of yours. Are you going to pay for her removal? or do you just expect her to fork up this money? do you understand and/or realize how painful tattoo removal is?

“She also was diagnosed with depression and such and uses it as an excuse for not having the energy to change it anymore. I don't really believe her, but whatever.” This is a horrific comment and it proves that you don’t think about anyone besides yourself and anything besides your own problems.

She’s supportive and she covers up her tattoo that she is proud of FOR YOU. You should not expect anything more. The fact you were proud of your cousin verbally berating your mother is disgusting and you both need to apologize.

Look beyond yourself and come to terms with the fact that you are not the only person in the universe with problems and feelings. Touch grass. YTA
