Not going to lie, Oliviaxox responding to Olivia liviray had me going for a moment.
Miss Olivia, you need to forget about that selfish young man and move on with your life. If you report those pictures being taken, you can be just as liable for their production because YOU took them. Taking and sitributing nude pictures of an underage individual (even it is yourself) is prosecutable for distribution of child pornography. You absolutely could be brought down for that, too. That is why parents try to stop their underage kids from sending nudes of themselves, they aren't trying to be buzzkills or stop their kids from having fun or being individuals; IT IS HIGHLY ILLEGAL.
Rest up, relax, calm yourself down and stop focusing on the problem. Focus instead on the solution; since you have this problem, is there any way to fix it and prevent it from happening again? Those are your important questions.
For your own health, leave that young man alone. He wasn't supportive of you when you needed it and he took steps to further deal you emotional harm, that was extremely callous of him and he only cared about you insofar as you made him happy under his own terms. You are better off without him.
Let him go, and stop blaming yourself. You don't have to hurt yourself to express your feelings, young lady. You don't have to carve into your skin to gain a sense of control, and you don't have to scar yourself to feel better. Mary Lambert said it best: "You don't have to only know how to exist when you feel wanted." It is perfectly okay to come to terms with yourself and love yourself FOR yourself, for nobody's benefit but your own, and with nobody's permission but your own. You don't have to get someone else's permission to be happy.
Look into a mirror and tell that hurt young lady staring back at you that it is okay for her to love herself. You don't have to live this way and the pain you feel now will not last forever. Stop placing conditions on your worthiness and esteem yourself for your own sake, reject those awful thoughts of not being good enough, let yourself see the good in yourself and love yourself for who you are.
Always remember that you deserve the same chance as anyone else at pursuing your own happiness. Never allow anyone or anything to stifle your will to live happily, not even yourself. Most importantly, never forget that you matter, and you are not alone.
