Method to stop horny urges🙃

I just ended my third serious relationship. 

At this point of my mid twenty I'm getting tired of love, and wanted to focus on other things in life. Now, I've never been without a partner since 17 so idk how to not being without with a man for forever, anybody know a pill or any method to kill the horny? Before it kick in, I'm afraid I might fantasy my ex or someone other guys and make a mistake again... I have depression and it's very hard for me once I fall in love and for them to love me without me severely depressed. I know how this goes... and I don't need another man. I just want to kill off what my body might ask for in another two weeks and every other two weeks until forever lol
